  • Managed code (C#) vs Matlabs and C++ for speed

    - by dotnetdev
    Hi, I am about to start developing an edge detection system (once I've read through a couple of books, which I'm doing so at good speed), but one thing I am wondering is the speed of an app like Matlabs (which can compile code to C++) vs AFORGE.NET for edge detecton. Is unmanaged code generally faster? Thanks

  • Core Location and speed measurements

    - by Krumelur
    Does anyone know if Core Location in the iPhone OS uses anything but simple vector math to calculate speed? I've read that the GPS system can provide speed measurements that can be accurate when position is not (I believe using the Doppler shifts of the signals). I've tried and failed to see if the iPhone does this. The question is basically, does this data contain information or is it just convenience functions, using (filtered?) location data?

  • Poor upload/download speed on 2 x ADSL lines into a Cisco 2621XM

    - by 2020mobile
    Hi, Sorry never been on this site before so I apologise if not the right section or even forum. I have users complaining of very slow internetn connectivity on site and have checked with our ISP who have said that the line is testing at 8mb. We have 2 x BT lines that have our ISP broadand on them. Both lines go into a Cisco 2600 series router that then has a PIX firewall off that. Connectivity is successful just gone really slow and unable to download anything. Config is below: version 12.3 no service pad service tcp-keepalives-in service tcp-keepalives-out service timestamps debug datetime msec service timestamps log datetime msec service password-encryption ! hostname ROUTER-ADSL-INTERNET ! logging buffered 16384 informational enable secret xxx enable password xxx ! username xxx username xxx clock summer-time UK recurring last Sun Mar 1:00 last Sun Oct 1:00 aaa new-model ! ! aaa authentication login default local aaa authorization exec default local aaa session-id common ip subnet-zero no ip source-route ! ! ! ip audit notify log ip audit po max-events 100 no ip bootp server ip name-server 213.208.106.212 no mpls ldp logging neighbor-changes no ftp-server write-enable ! ! ! ! ! ! ! ! ! ! no voice hpi capture buffer no voice hpi capture destination ! ! ! ! ! ! ! ! interface ATM0/0 description 01270 111111 no ip address no atm ilmi-keepalive pvc 0/38 encapsulation aal5mux ppp dialer dialer pool-member 1 ! dsl operating-mode auto ! interface FastEthernet0/0 ip address 82.133.32.9 255.255.255.248 shutdown speed 100 full-duplex no cdp enable ! interface ATM0/1 description 01270 222222 no ip address no atm ilmi-keepalive pvc 0/38 encapsulation aal5mux ppp dialer dialer pool-member 1 ! dsl operating-mode auto ! interface FastEthernet0/1 ip address 217.146.115.49 255.255.255.240 duplex auto speed auto no cdp enable ! interface Dialer0 ip address 217.146.115.250 255.255.255.248 encapsulation ppp dialer pool 1 dialer-group 1 ppp authentication chap callin ppp chap hostname [email protected] ppp chap password 7 xxxxx ppp multilink ! ip classless ip route 0.0.0.0 0.0.0.0 Dialer0 ! no ip http server no ip http secure-server ! no logging trap access-list 10 permit 217.146.115.50 access-list 10 permit 82.133.32.10 access-list 10 deny any access-list 22 permit 217.146.115.50 access-list 22 permit 217.206.239.86 access-list 22 permit 82.133.32.10 access-list 22 deny any dialer-list 1 protocol ip permit no cdp run ! ! snmp-server community xxxxxx RO 10 snmp-server enable traps tty radius-server authorization permit missing Service-Type ! ! ! ! ! ! line con 0 exec-timeout 5 0 password 7 xxxxxx line aux 0 no exec line vty 0 4 access-class 22 in exec-timeout 5 0 password 7 xxxxxx transport input telnet ssh transport output none line vty 5 15 password 7 xxxxxx transport input telnet ssh ! ntp clock-period 17180095 ntp server 130.88.200.98 ! ! end Now my knowledge is very limited but ISP have said that while the lines are bonded each needs a seperate login as they've recently changed their L2TP router and that enforces the use of seperate logins - when the lines were configured we were given two logins.

  • Internet speed is suddenly slow only on my laptop, but it's normal in other devices

    - by Wael
    I have a TP-Link router connected to a ZTE modem, with 2 laptops, a tablet, 2 phones connected via the router's WiFi, and an additional desktop connected via ethernet to the router. Today, my laptop started to have a very slow connection to the internet, which at first I thought it was the operator's problem to find out later on that it works fine on other devices. I tried to connect directly via WiFi to the modem, but it was as slow. I cannot access facebook at all, google takes forever to do a search, and youtube barely works. The weird thing though, is that when youtube does work, the streaming is full speed. This happens also when I download a file! My browse is Firefox, but I used Chrome and IE9 with the same results. I work on Windows 7 Thanks for any advices.

  • Slower wireless speed in Ubuntu 12.04 (64-bit) on Asus USB-N13

    - by PhantonTurtle
    I have an Asus USB-N13 which I use for wireless internet on my desktop. The download speed I get on Windows 7 (dual-boot) is 15.22 Mbps. On Ubuntu 12.04 (64-bit) I can only get 1.09 Mbps. I asked a question about this on the Ubuntu forums as well, but I did not get an answer. Here is the output from lsmod | grep rt which gives me, parport_pc 32866 0 rtl8192cu 103297 0 rtl8192c_common 75767 1 rtl8192cu rtlwifi 111202 1 rtl8192cu mac80211 506816 3 rtl8192cu,rtl8192c_common,rtlwifi cfg80211 205544 2 rtlwifi,mac80211 parport 46562 3 parport_pc,ppdev,lp I installed the drivers from Realtek (my chipset is Realtek, not Ralink) but that did not work.

  • RAID Read/Write Speed Gradually Slows

    - by Nalandial
    This is actually a server at home, but I felt it was sufficiently complicated as to not have it on SuperUser and could easily apply to a professional situation. I have a file server running Debian (Lenny 5.0.4), and it has an XFS LVM on top of a RAID 5 with the OS drive separate from the RAID. It's also running apache, samba, and postgresql. Side note: before anyone asks, I'm using RAID5 because I get more bang for the buck on raw drive space, and still have some fault tolerance. When the box is started (via shutdown or reboot) reading/writing to it's samba share maxes out the gigabit network connection. Over time, this slowly degrades eventually becoming < 10MB/s; however, when rebooted the speed returns to maxing out the connection. Why is this happening, and is there a way to 'clear' out whatever's causing it without taking the server down? Thanks in advance!

  • NIC: Changing Link Speed & Duplex to Full Duplex Is Drastically Slower

    - by rism
    I have an old Win Xp box with a 100 PRO/100 VE NIC and connecting to a Win 7 box with gigabit NIC via an ASUS gigabit router and peer to peer. I was getting 76% network utilisation on the XP machine using AUTO as the value for Link Speed and Duplex which is fine. But I decided to see what would happen if i selected Full Duplex 100Mbps on the XP box. I thought at worst it would be as good as auto detect since the Win 7 box it's transferring to is faster. Instead network utilisation dropped to 0.12% (as in a 10th of a percent) and the transfers just timed out. No biggie to reverse back to Auto but my question is why is full duplex such a dog? Im not "stuck" but just dont understand. There are only 2 machines here connecting through a router so i cant see how that would cause alot of collisions etc (if thats the problem).

  • Netgear WNR1000 WiFi speed

    - by Kamil Klimek
    I have Netgear WNR1000 150N, Macbook Pro 13" with Broadcom BCM43xx 1.0, Network connection 60mbps When I connect through the cable I easily get around 60mbps. When I go through the WiFi it's capable to get only 32mbps at tops. Any ideas why is that? Is that my router limitation or maybe my WiFi card? If it is routers fault what router would you suggest. Best router would be with usb port for external hard drive. Forgot to add screenshot with connection details: Szybkosc transmisji == Transmission speed

  • What does the fan speed sensor really report?

    - by T. Verron
    I have an overheating issue on my netbook (ASUS EeePC 1015PW), which I'm trying to troubleshoot. Using lm-sensors while overheating gave me this output : acpitz-virtual-0 Adapter: Virtual device temp1: +86.0°C (crit = +100.0°C) eeepc-isa-0000 Adapter: ISA adapter fan1: 4089 RPM coretemp-isa-0000 Adapter: ISA adapter Core 0: +82.0°C (crit = +100.0°C) Core 1: +80.0°C (crit = +100.0°C) But I can't hear the fan. So I enabled manual pwm controling and set the fan to full speed, and after a few minutes I got this output : acpitz-virtual-0 Adapter: Virtual device temp1: +65.0°C (crit = +100.0°C) eeepc-isa-0000 Adapter: ISA adapter fan1: 4016 RPM coretemp-isa-0000 Adapter: ISA adapter Core 0: +62.0°C (crit = +100.0°C) Core 1: +58.0°C (crit = +100.0°C) And this time I could hear the fan spinning. So there's quite obviously an issue with either fan control or fan monitoring. Hence the question : what kind of physical information does the fan sensor really report? Thank you PS. I should have added that the computer is a small, hard-to-disassemble netbook, so I can't and don't want to try experiments like "block the fan and see what the sensor reports".

  • Seasgate GoFlex NAS + Horrible Speed = Bad Experience

    - by Jon H
    I am having issues with transfer speeds from my desktop PC to my NAS. I have my NAS hooked up to a Gigabit Gateway as well as my Desktop with Cat 5e. I see up to 4.0 MB/Second Transfer Rates, the normal is about 2.5 MB/Seconds. There is 3 Partitions on my NAS, Public, Private, Backup. When I transfer from Private to Public I see the speeds above. If its under the same partition almost instant. I was wondering if the speeds I am seeing is in due to my Computer or the NAS. I was looking into building my own Media Server in due to these horrible speeds. Is their anything I can do in the mean time to speed this up? Motherboard = M3970AM-HP (Angelica) Processor = AMD FX 6100 Ram = 10GB PC3-10600 MB/sec Hard Drive (1) = 1.5TB SATA 3.0GB 5400RPM Hard Drive (2) = 120GB SATA SSD NAS = Seagate 3TB Go Flex Home Connection (1) = 1000 Base T Connection (2) = Wireless N

  • Tool to bulk speed up/convert an audio file

    - by User1
    I want to listen to certain podcasts on my phone but I have two common problems: The audio is in some weird format (some don't play on my phone). The audio is slow. I want to use something like sox or avconv to bulk convert the files. Since this is just voice and going on a cell phone, small low-quality files would be best for me. I had some good success using avconv: avconv -i weird.wma normal.ogg Unforunately, this command creates an enormous ogg file and I can't get it play faster. Ideally, this particular file would play at 170% of the original speed.

  • How SSD hard drive affected speed of your website (asp.net/linq/ms sql database)

    - by Sergey Osypchuk
    I have a small database (<1G) But we have a lot of complex logi? in website and client complains on render time, which is 3-5 seconds. We are not google, and thousands of users a day is our dream, so size is not a problem, but speed is important. Can anybody share with experience with SSD drives for ASP.NET (MVC)/LINQ/MS SQL based application ? How you performance increased? UPDATE: this whitepaper states that it will be 20 times faster. http://www.texmemsys.com/files/f000174.pdf

  • Why doesn't my computer work at full speed?

    - by kubilas
    My motherboard is a Gigabyte GA-8I915PL-G with an Intel Pentium 4 630 3,0 GHz which doesn't run at it's default speed. It's currently at FSB 800, CPU Host 200 and CPU 3000 MHz; but sometimes it runs at FSB 533, CPU Host 133 and CPU 2025 MHz. Sometimes it's even at FSB 75 and CPU 1128 MHz. When I configure the default settings in Easy Tune then my computer doesn't work. Sometimes I need to clear the CMOS so I can set the default settings in the BIOS, but that doesn't always help. I've updated the BIOS, what else can I do to fix this problem?

  • Virtualbox, slow upload speed using nat

    - by user1622094
    Im running Virtualbox on a Ubuntu 12.04 server (host) and I'm running a Windows 7 as guest os. Im using the (virtual) Intel PRO/1000 MT network card. I get good network performance for download using both nat and bridged network settings but upload speed is really slow using nat. I have tied this on tow different servers, one brand new, and one a several years old, both gave the same result. If you can explain this behavior or have ideas of further test I can perform please let me know.

  • Disk controller speed responsible for slow write speeds?

    - by vizvayu
    I have question. I'm using ESXi 4.0U1 in an IBM x3200M2 with an integrated LSI 1064e RAID controller, without any kind of cache. I have 3 250GB HOT-SWAP SATA HDs configured in RAID1E (IME). ESXi works fine, read speed are quite OK, but write speeds are incredible slow, never more than 8MB/s, and this is the best case scenario, benchmarking with iozone streaming writes, using a VMWare Paravirtual controller and with only this VM active, no swapping of any kind (total vm memory reserved). Already wrote to IBM but I don't have any kind of pay support so they didn't even answered, so I'm just wondering... anybody has any experience with a similar setup? I just want to be sure this is hardware related and can't be fixed with some kind of config option, because I'm thinking on buying a new RAID controller (Adaptec 2405 looks nice). Thanks again!

  • Nginx and low-speed connections: request terminates after 253 seconds

    - by meze
    I'm trying to make nginx to handle static files. All is working fine except that when I throttle my connection speed to 8kbit/s, the loading process of a file just stops after 253-255 seconds (4.2 min according to chrome). No error in the log, the status code is 200 but the response is received partially. If I disable nginx and make apache to send the same file - it loads successfully after 10 minutes. The config I use for debugging is: client_header_buffer_size 16k; large_client_header_buffers 4 8k; client_max_body_size 50m; client_body_buffer_size 16k; client_header_timeout 20m; client_body_timeout 20m; send_timeout 20m; Did i miss some configurations?

  • Slow speed for UFS mounted drive in Linux

    - by Incredible
    Hi, I have a disk that has Sun OS disk, (ufs filesystem). And I want to mount it in my debain machine with read/write mode. Since by deafult linux doesn't support write to ufs filesystem. I had to recompile the kernel by setting to the flag CONFIG_UFS_FS_WRITE=y. Now I am able to write to the filesystem, but the read/write speed is very slow. It is around 120 KB/s. Any idea what is wrong and how to resolve this issue? Thank you in advance.

  • CPU and Motherboard clock speeds

    - by NZHammer
    I have been doing some reading about CPU clock speeds and how CPU clock speeds are calculated. After reading several articles, I have come to the understanding that your CPU clock speed is determined by: CPU clock speed = cpu multiplier x mobo clock speed A few questions came about after reading this which I cannot seem to find the answer to anywhere: If the CPU clock speed is dependent upon the mobo clock speed, then how is the clock speed of the CPU predetermined upon buying the CPU (i.e. written on the box without knowing what mobo is being used)? After installation, does the CPU adjust it's multiplier based upon the mobo clock speed to achieve advertised speeds? For example, if the CPU clocks speed is advertised at 2.4GHz and the mobo clock speed is 100MHz, will the multiplier be automatically set to 24x? Why does mobo clock speed seem to not be very important / talked about? For example, when I search on Newegg, mobo clock speed never seems to be listed. When I search enthusiast forums and overclocking forums, mobo clock speed is rarely mentioned. To me, it seems like the mobo clock speed would be pretty important. If I am understanding things correctly, a lower mobo clock speed means that you CPU must work harder to achieve advertised clock speeds. I guess that I should stop there with the questions for now, as I may be asking my questions based on incorrect assumptions. Thanks!

  • Collision point of 2 curves in a 3d-room

    - by Frank
    Hello, i am programming a small game for quite some time. We started coding a small FPS-Shooter inside of a project at school to get a bit experience using directX. I dont know why, but i couldnt stop the project and started programming at home aswell. At the moment i am trying to create some small AI. Of cause thats definatlly not easy, but thats my personal goal anyways. The topic could prolly fill multiple books hehe. I've got the walking part of my bots done so far. They walk along a scriped path. I am not working on the "aiming" of the bots. While programming that i hit on some math problem i couldnt solve yet. I hope of your input on this to help me get further. Concepts, ideas and everything else are highly appreciated. Problem: Calculate the position (D3DXVECTOR3) where the curve of the projectile (depends on gravity, speed), hit the curved of the enemys walking path (depends on speed). We assume that the enemy walks in a constant line. Known variables: float projectilSpeed = 2000 m/s //speed of the projectile per second float gravitation = 9.81 m/s^2 //of cause the gravity lol D3DXVECTOR3 targetPosition //position of the target stored in a vector (x,y,z) D3DXVECTOR3 projectilePosition //position of the projectile D3DXVECTOR3 targetSpeed //stores the change of the targets position in the last second Variabledefinition ProjectilePosition at time of collision = ProjectilePos_t TargetPosition at time of collision = TargetPos_t ProjectilePosition at time 0, now = ProjectilePos_0 TargetPosition at time 0, now = TargetPos_0 Time to impact = t Aim-angle = theta My try: Found a formular to calculate "drop" (Drop of the projectile based on the gravity) on Wikipedia: float drop = 0.5f * gravity * t * t The speed of the projectile has a horizontal and a vertical part.. Found a formular for that on wikipedia aswell: ProjectilVelocity.x = projectilSpeed * cos(theta) ProjectilVelocity.y = projectilSpeed * sin(theta) So i would assume this is true for the projectile curve: ProjectilePos_t.x = ProjectilePos_0.x + ProjectileSpeed * t ProjectilePos_t.y = ProjectilePos_0.y + ProjectileSpeed * t + 0.5f * gravity * t * t ProjectilePos_t.z = ProjectilePos_0.z + ProjectileSpeed * t The target walk with a constant speed, so we can determine his curve by this: TargetPos_t = TargetPos_0 + TargetSpeed * D3DXVECTOR3(t, t, t) Now i dont know how to continue. I have to solve it somehow to get a hold on the time to impact somehow. As a basic formular i could use: float time = distanz / projectileSpeed But that wouldnt be truly correct as it would assume a linear "Trajectory". We just find this behaivor when using a rocket. I hope i was able to explain the problem as much as possible. If there are questions left, feel free to ask me! Greets from germany, Frank

  • determining the starting speed for an accelerated animation (in flash/actionscript but it's a math question)

    - by vulkanino
    This question burns my brain. I have an object on a plane, but for the sake of simplicity let's work just on a single dimension, thus the object has a starting position xs. I know the ending position xe. The object has to move from starting to ending position with an accelerated (acceleration=a) movement. I know the velocity the object has to have at the ending position (=ve). In my special case the ending speed is zero, but of course I need a general formula. The only unknown is the starting velocity vs. The objects starts with vs in xs and ends with ve in xe, moving along a space x with an acceleration a in a time t. Since I'm working with flash, space is expressed in pixels, time is expressed in frames (but you can reason in terms of seconds, it's easy to convert knowing the frames-per-second). In the animation loop (think onEnterFrame) I compute the new velocity and the new position with (a=0.4 for example): vx *= a (same for vy) x += vx (same for y) I want the entire animation to last, say, 2 seconds, which at 30 fps is 60 frames. Now you know that in 60 frames my object has to move from xs to xe with a constant deceleration so that the ending speed is 0. How do I compute the starting speed vs? Maybe there's a simpler way to do this in Flash, but I am now interested in the math/physics behind this.
