• Internet Speed for Webserver

  - by René

  That should be kind of dumb question in comparison to all other questions here. What minimum upload and download is required for a small home webserver with one webpage? Or is there a schema that shows me the required upload and download speed for a number of visitors? We talk about a Windows Server, but not really sure this is relevant. That's just for a practice project.

• How do I see the negotiated wireless speed in Windows 7 and OS X

  - by user26453

  In Windows XP when I connected to a network it would list the speed at which I connected, e.g. 54 mbps, 11 mbps, etc. Where can I see the same information in in either Windows 7 or OS X? Since upgrading from XP I cannot see this info in Windows 7 and I've never been able to see it in OS X.

• Determining speed (class) of USB on PC

  - by Thomas Matthews

  Is there a method for determining the speed of a USB port on a Windows XP PC, without using a USB protocol analyzer? I'm looking for something simple, such as looking at the Device Manager. I would like to hook up some USB equipment to a USB 2.0 port, rather than the slower USB 1.0 or 1.1.

• What is more important for speed: Processor Speed or RAM?

  - by Jake

  I am about to buy a desktop, I narrowed it down to two choices, both are virtually identical (even in terms of price) but one has 4 GB of RAM and a 3.7 GHZ CPU the other has 8GB of RAM and a 2.7 GHZ CPU Which is the better choice for speed? Also as a side question, what is better: a 2GB stick of DDR2 RAM or a 4GB stick of DDR3?

• High CPU from httpd process

  - by KHWeb

  I am currently getting high CPU on a server that is just running a couple of sites with very low traffic. One of the sites is in still development going live soon. However, this site is very very slow...When browsing through its pages I can see that the CPU goes from 30% to 100% for httpd (see top output below). I have tuned httpd & MySQL, Apache Solr, Tomcat for high performance, and I am using APC. Not sure what to do from here or how to find the culprit as I have a bunch of messages on the httpd log and have been chasing dead ends for some time...any help is greatly appreciated.

• High Availability with 2 servers?

  - by Tom R

  Is it possible to have a high availability setup with 2 servers? Running Windows Web Server 2008 and MSSQL Web Edition (as I know Express isn't supported)? Getting to the point where our one dedicated server needs scaled out and going to a second server already more than doubles the cost as need to use Web Edition rather than Express (db is only 500MB).

• high resolution on small screen size

  - by vishesh

  I have recently got an intel ultrabook,but its screen size is 13.3' and the native resolution is 1600X900.So the problem is that the letters that appear on screen are very small.Reducing resolution blurs the display and making everything bigger also doesn't feel very good.is there a way to get around this problem without changing hardware. I am even ok with this high resolution but I am concerned about the harmful effects it might have on my eyes in long term. Any advice will be very useful.Please help

• Android Game Development problem with Speed = Distance / Time

  - by Charlton Santana

  I have been coding speed for an object. I have made it so the object will move from one end of the screen to another at a speed depending on the screen size, at the monemt I have made it so it will take one second to pass the screen. So i have worked out the speed in code but when I go to assign the speed it tells me to force close and i do not understand why. Here is the code: MainGame Code: @Override protected void onDraw(Canvas canvas) { setBlockSpeed(getWidth()); } private int blockSpeed; private void setBlockSpeed(int screenWidth){ Log.d(TAG, "screenWidth " + screenWidth); blockSpeed = screenWidth / 100; // 100 is the FPS.. i want it to take 1 second to pass the screen Math.round(blockSpeed); // to make it a whole number block.speed = blockSpeed; // this is line 318!! if i put eg block.speed = 8; it still tells me to force close } Block.java Code: public int speed; public void draw(Canvas canvas) { canvas.drawBitmap(bitmap, x - (bitmap.getWidth() / 2), y - (bitmap.getHeight() / 2), null); if(dontmove == 0){ this.x -= speed; // if it was eg this.x -= 18; it would not have an error } } The exception 06-08 13:22:34.315: E/AndroidRuntime(2801): FATAL EXCEPTION: Thread-11 06-08 13:22:34.315: E/AndroidRuntime(2801): java.lang.NullPointerException 06-08 13:22:34.315: E/AndroidRuntime(2801): at com.charltonsantana.game.MainGame.setBlockSpeed(MainGame.java:318) 06-08 13:22:34.315: E/AndroidRuntime(2801): at com.charltonsantana.game.MainGame.onDraw(MainGame.java:351) 06-08 13:22:34.315: E/AndroidRuntime(2801): at com.charltonsantana.game.MainThread.run(MainThread.java:64)

• Why not have a High Level Language based OS? Are Low Level Languages more efficient?

  - by rtindru

  Without being presumptuous, I would like you to consider the possibility of this. Most OS today are based on pretty low level languages (mainly C/C++) Even the new ones such as Android uses JNI & underlying implementation is in C In fact, (this is a personal observation) many programs written in C run a lot faster than their high level counterparts (eg: Transmission (a bittorrent client on Ubuntu) is a whole lot faster than Vuze(Java) or Deluge(Python)). Even python compilers are written in C, although PyPy is an exception. So is there a particular reason for this? Why is it that all our so called "High Level Languages" with the great "OOP" concepts can't be used in making a solid OS? So I have 2 questions basically. Why are applications written in low level languages more efficient than their HLL counterparts? Do low level languages perform better for the simple reason that they are low level and are translated to machine code easier? Why do we not have a full fledged OS based entirely on a High Level Language?

• Processor always at max speed

  - by Pratyush Nalam

  I am running Windows 8 Pro on an Apple MacBook Pro 9,1 Mid 2012 15 inch non retina. It has a Core i7-3720 QM CPU @ 2.6 GHz. For the past few days, I have noticed that it is constantly running at max speed which is 2.59 GHz. Before, it used to run at 1.5 - 1.8 GHz on normal usage. And, the weirder thing is that CPU usage is minimal. Screenshot: So, what is the reason for this? And is it harmful?

• Software to measure the speed of http browser connections

  - by Dan Revell

  I'm trying to gather some ammunition about my ISP and it's aggressive traffic shaping of particular websites. So I'm looking for an application that will allow me to see what speeds I get to particular websites. I want to open a browser connection to a particular video streaming website for example and see the speed of the connection that gets made, be it http or plain tcp. I'm after something along the lines of TCPView but unfortunately this doesn't include transfer speeds. I'm half tempted to write one myself but hopefully something will already be out there that does the job.

• How can I limit CD drive speed while on the live CD to avoid drive noise?

  - by iugamarian

  I sometimes disconect my harddisks for the weeks while only using the internet and I use the Ubuntu Live CD. But every time it needs something while in live desktop it accelerates and makes a lot of noise, also the acceleration takes too long. I want lower drive speed than acceleration lags, because acceleration lags stop me completly exactly when I need something. How can I lower the CD drive speed, say to maximum 16x, without restarting? I can't restart because I only use the CD drive, no harddisks, no flash disks, no network disks. Edit: No USB drives. Setcd does not work for the live session.

• Mobile Intel 965 vs 4 Series chipset speed differences

  - by graham.reeds

  A client of ours is having a problem panning on a mapping application that we write on their panasonic toughbooks (CF-19's). One of their toughbooks the panning is fairly smooth while on the other it is really slow. Doesn't help that they have all the settings turned up, but I would of thought any reasonably new graphics card (even shared memory) would have more than adequate graphic speed. I am pretty sure that the graphic adapter is to blame, but I can't find anything out about either chipset (level of acceleration, non-problems, etc). All I get is the intel data sheets. The faster panning one is on the Mobile Intel 4 Series Express Chipset while the slower is on the Mobile Intel 965 Express Chipset. Is this expected? Does it sound like a driver problem? They both have the same amount of ram and same cpu.

• How do you enhance your websites speed without compromising the design and access?

  - by Thorn007

  How do you enhance your websites load speed without killing the design and accessibility? File compression, CDN, Gzip? What are the best tools for doing so? For example, Google has optimized their site without compromising the design. Also, many website can kill the purity of their images with compression. Is there a way, more or lest best practice, to increase speed without compromising the design and accessibility? Note: sorry for being so vague but I don't know how else to phrase this question.

  I try and try and try to performance and fix problem with gluster, i try all. I served on gluster webpages, php files, images etc. I have problem after update from 3.3.0 to 3.3.1. I try 3.4 when i think maybe fix it but still the same problem. I temporarily have 1 brick, but before upgrade will be fine. Config: Volume Name: ... Type: Replicate Volume ID: ...

• Providing high availability and failover using MySQL on EC2

  - by crb

  I would like to have a highly-available MySQL system, with automatic failover, running on Amazon EC2 instances. The standard approach to solving this is problem Heartbeat + DRBD, but I've found a lot of posts suggesting DRBD doesn't work on EC2, though none saying exactly why. Obviously, a serial heartbeat or distinct network is out of the question in the virtualised environment. It would also be good to have the different servers be in different availability zones, but we're getting into a much harder problem there. What are peoples' opinion on having a high uptime solution in "the cloud"?

• Most suitable high availability solution

  - by Alex Bagnolini

  My company is hosting a website in a server with IIS, SQL Server and a 3rd party windows service (written in C#, source code available for amendments). We bought a new identical server, composed by: 1x Quad Core, 12GB RAM, 4x160GB SATA Raid 5, Windows Server 2008 R2 Datacenter, Public IP. We aim to put all webpages and the 3rd party windows service in an high-availability state. After some lab-testing on how to configure Failover Clustering and Hyper-V, we have deep doubts on what the "best" solution would be, by "best" meaning maintainable and able to correctly handle a physical server failure. Any suggestion on how we should configure the two servers? We don't need all the configuration's step, just an hint on the right direction to follow.

  I have a video of a tennis match whose Resolution = 1280 * 720 Codec = H264 Frame rate = 50fps (Copy paste from info given by totem media player) My laptop is not powerful enough to play this video smoothly. How can I reduce the frame-rate of this video so that my laptop can play it? I have observed that my laptop can play videos with 25fps without an issue. I use ubuntu. I wouldn't mind using windows to edit/re-encode this video.

• VMware Virtual vCenter and High Availability

  - by rufo

  To continue with this question: Should be Vmware vCenter server high available? According to the response there even if vCenter is down HA will continue to work. So, if my vCenter is a VM, using the express sql edition in the same VM, and that VM is hosted in the same cluster it manages (and the cluster is setup for HA): Am I correct to assume that if the host that hosts the vCenter goes down HA will vmotion the vCenter VM to another host and it will continue to function? BTW: my environment is small, two ESXi 5.0 hosts, with about 50 VMs, using iSCSI shared storaged for everything.

• High availability for Windows Service under Windows Server 2003

  - by empi

  Hi. I have a following situation: I need to deploy a windows service that listens for incoming request on tcp port (basically WCF service). I have a High Availability requirement - the service must be deployed on two servers and if the service stops (only the service, not the whole server) on one server, all the requests must be redirected to the second one. For me it looks like a basic failover scenario. How can I achieve this on Windows Server 2003? Should I use Microsoft Cluster Service or Network Load Balancing? The important part is that the process of swapping the servers should not concern the clients (the client must see only single address / single host or domain name). Thanks in advance for help.

• Very fast Laptop Heating due to very high CPU usage by dwm.exe

  - by Sushan Shrestha

  My laptop gets heated very fast and when I check the task manager, I find dwm.exe consuming very high CPU (mostly 100%). In the beginning I found the message "The graphic adapter has been stopped and recovered".Also I am getting one error message "Cidaemon.exe has stopped working" very frequently. During this period also, cpu usage is 100% which is consumed by dwm.exe. I have run ccleaner and Kingsoft PC doctor monitor to fix the register problem but the problem has not been solved. My display adaptor is : NVIDIA NVS 5200M. After the driver update, I am not getting "The graphic adapter has been stopped and recovered" but dwm.exe is still consuming 100% CPU one time in about 5 mins. Multiple restarts has not helped. Laptop Model: Dell Latitude E6430. Thanks in advance.

• Connection speed drops from 1 Gbps to 10 Mbps (Vista 64)

  - by Kevin Hakanson

  I recently got a Windows Home Server (HP MediaSmart Server EX490) setup so I could do backups and other things. However, I am having trouble on my Vista 64 PC. The backup will be making great progress, then it will just slow down. At one point, I noticed the lights on my Netgear GS105 indicated it was not using a 1000 Mbps connection, but a 10 Mbps one. I checked the Status of Local Area Connection (Intel(R) 82567V-2 Gigabit Network Connection) and that also showed the same slow speed. This has happened several times in the last couple days. When I disabled the network device, and then enabled it, it established the 1 Gpbs connection again. However, some of the times the Sent Bytes Activity on the Status windows indicate that the data flow is still slow (100 to 1000 bytes every couple seconds). Obviously, at this rate I could backup faster to floppy disk. :) My question is how to diagnose and fix this problem. When I look at the Administrative Events, I do a Errors: Bonjour Service 456: ERROR: read_msg errno 10054 (An existing connection was forcibly closed by the remote host.) And a Warning: e1yexpress Intel(R) 82567V-2 Gigabit Network Connection Link has been disconnected. I am suspicious there is some power saving mode. I found a post suggesting System Idle Power Saver(SIPS) may be the issue. I am going to try that, but looking for other suggestions or diagnostic advice. I have several new items in this configuration: server, client software, switch and cat6 cables.
