• Speed Problem with Wireless Connectivity on Cisco 877w

  - by Carl Crawley

  Having a bit of a weird one with my local LAN setup. I recently installed a Cisco 877W router on my DSL2+ connection and all is working really well.. Upgraded the IOS to 12.4 and my wired clients are streaming connectivity superfast at 1.3mb/s. However, there seems to be an issue with my wireless clients - I can't seem to stream any data across the local wireless connection (LAN) and using the Internet, whilst responsive enough isn't really comparable with the wired connection speed. For example, all devices are connected to an 8 Port Gb switch on FE0 from the Router with a NAS disk and on my wired clients, I can transfer/stream etc absolutely fine - however, transferring a local 700Mb file on my local LAN estimates 7-8 hours to transfer :( The Wireless config is as follows : interface Dot11Radio0 description WIRELESS INTERFACE no ip address ! encryption mode ciphers tkip ! ssid [MySSID] ! speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 channel 2462 station-role root rts threshold 2312 world-mode dot11d country GB indoor bridge-group 1 bridge-group 1 subscriber-loop-control bridge-group 1 spanning-disabled bridge-group 1 block-unknown-source no bridge-group 1 source-learning no bridge-group 1 unicast-flooding All devices are connected to the Gb Switch which is connected to FE0 with the following: Hardware is Fast Ethernet, address is 0021.a03e.6519 (bia 0021.a03e.6519) Description: Uplink to Switch MTU 1500 bytes, BW 100000 Kbit/sec, DLY 100 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex, 100Mb/s ARP type: ARPA, ARP Timeout 04:00:00 Last input never, output never, output hang never Last clearing of "show interface" counters never Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0 Queueing strategy: fifo Output queue: 0/40 (size/max) 5 minute input rate 14000 bits/sec, 19 packets/sec 5 minute output rate 167000 bits/sec, 23 packets/sec 177365 packets input, 52089562 bytes, 0 no buffer Received 919 broadcasts, 0 runts, 0 giants, 0 throttles 260 input errors, 260 CRC, 0 frame, 0 overrun, 0 ignored 0 input packets with dribble condition detected 156673 packets output, 106218222 bytes, 0 underruns 0 output errors, 0 collisions, 2 interface resets 0 babbles, 0 late collision, 0 deferred 0 lost carrier, 0 no carrier 0 output buffer failures, 0 output buffers swapped out Not sure why I'm having problems on the wireless and I've reached the end of my Cisco knowledge... Thanks for any pointers! Carl

• local web application vs desktop application speed?

  - by Josh

  Which one would be faster - a local web app gui made with something like qooxdoo or a desktop app? How much speed difference would there be expected? I would prefer creating a web app which could in the future be shared than creating a desktop gui which is specialized on certain gui toolkits.

• How to speed up 'cold start' of .NET component called from VB6 app

  - by Craig Johnston

  I have a VB6 app which brings up a form by invoking a .NET DLL, but the problem is that this form takes almost 5 seconds to appear after a menu item in the VB6 app is selected. How can I speed this up? I'm thinking that one possible solution is to load the Form from the .NET DLL during the splash screen of the VB6 app but make invisible or somehow not show it, and then when the menu item is selected I will make it show or visible. What are my options?

• PHP Increasing write to page speed.

  - by Frederico

  I'm currently writing out xml and have done the following: header ("content-type: text/xml"); header ("content-length: ".strlen($xml)); $xml being the xml to be written out. I'm near about 1.8 megs of text (which I found via firebug), it seems as the writing is taking more time than the script to run.. is there a way to increase this write speed? Thank you in advance.

• Programatically change cursor speed in windows

  - by Juan Manuel Formoso

  Since getting a satisfactory answer on SuperUser is very difficult, I want to rephrase this question and ask: Is there any way to programatically detect a mouse was plugged in the usb port, and change the cursor speed in windows (perhaps through an API)? I'd like to use C#, but I'm open to any language that can run on a windows 7 machine.

• High speed matrix manipulation in c#?

  - by Donnie

  I'm working on some image manipulation code in c# and need to do some matrix operations (specifically 2D convolution). I have the code written in matlab which uses the conv2 function ... is there a library for C# / .NET that does good high-speed matrix manipulations? I'd be fine if it requires some specific GPU and does the matrix math on-GPU if that's what it takes.

• Helping Kohana 3 ORM to speed up a little

  - by Luke

  I noticed that Kohana 3 ORM runs a "SHOW FULL COLUMNS" for each of my models when I start using them: SHOW FULL COLUMNS FROM `mytable` This query might take a few clock cycles to execute (in the Kohana profiler it's actually the slowest of all queries ran in my current app). Is there a way to help Kohana 3 ORM to speed up by disabling this behaviour and explicitly define the columns in my models instead?

• How to speed up/slow down application's 'time'

  - by overboming

  I guess I am not saying it right in the title. What I intend to do is to hook to some system api,like a time interrupt happens every amount of time (which is how every application in the operating system interprets time) and make an application's call to this api return some bigger/smaller result. So from the point view of an applicaiton, time has been speed up or slow down. I have found some application on windows doing this, can anyone gives me some pointers on how to implement this on Mac OS X?

• How can I speed up Visual Studio 2010 text editor render speed?

  - by user144182

  Visual Studio 2010 moved to using WPF for rendering the editor. This is leading to slowdowns while I am editing code, especially if I'm running something else that uses other video capabilities. How can I speed this up? A new video card? New drivers? Settings? What technologies does WPF use to render and what video card would complement it?

• How is it possible to limit download speed?

  Lately I've asked this question. But the answer doesn't suit my demands, and I know that file hosting providers do manage to limit the speed. So I'm wondering what's the general algorithm/method to do that (I do mean downloading technique).

• microsoft access query speed...

  - by V.S.

  Hello everyone! I am now writing a report about MS Access and I can't find any information about its performance speed in comparison to other alternatives such as Micorsoft SQL Server, MySQL, Oracle, etc... It's obvious that MS Access is going to be the slowest among the rest, but there is no solid documents confirming this other than forums threads, and I don't have the time and resources to do the research myself :( Hoping for your help, V.S.

• In TCP/IP terms, how does a download speed limiter in an office work?

  - by TessellatingHeckler

  Assume an office of people, they want to limit HTTP downloads to a max of 40% bandwidth of their internet connection speed so that it doesn't block other traffic. We say "it's not supported in your firewall", and they say the inevitable line "we used to be able to do it with our Netgear/DLink/DrayTek". Thinking about it, a download is like this: HTTP GET request Server sends file data as TCP packets Client acknowledges receipt of TCP packets Repeat until download finished. The speed is determined by how fast the server sends data to you, and how fast you acknowledge it. So, to limit download speed, you have two choices: 1) Instruct the server to send data to you more slowly - and I don't think there's any protocol feature to request that in TCP or HTTP. 2) Acknowledge packets more slowly by limiting your upload speed, and also ruin your upload speed. How do devices do this limiting? Is there a standard way?
