How can I calculate the size of a T-SQL query in bytes transfered across the network? I know I can approximate it by examining data types of columns (varchars are an interesting twist though), but are there tools that'll give me the number of bytes (including and excluding TCP/IP headers) used up while transferring the query and its res...
All, I'm building a network intensive application to consume real time financial marketdata and the network team is suspicious regarding its bandwidth usage per instance. I'm trying to use the System.Diagnostic performance counter "Bytes Total/sec" in the "Network interface" to get an idea of my application footprint on the network. H...
I am currently using mod_cband with Apache 2.2 to throttle bandwidth on a server. Whenever the traffic exceeds my limits, apache delivers a 503 to some users. Instead I want it to simply block for a while until the rps/kbps is below limit again. Here are my settings: CBandSpeed 1024 100 300 CBandRemoteSpeed 10kb/s 3 2 ...
Hello. I am working on a community photo sharing site, and I need some way of controlling the bandwidth. For example I would like to set a maximum bandwidth allowed, which can be image size x the number of times the image was viewed. Similar to what a site like photobucket does (when they replace an image with a bandwidth exceeded image)...
I need to test the performance of application running on localhost as if it were in the online environment. I mean the performance test conducted by the network traffic simulation, limited bandwidth simulation, or other parameter as if it were online. could Apache Ab do the simulation? Thank u so much. ...
Hi. I want to broacast my screen, the problem is i've got very limited upload speed, if there are more than 2 clients screencast becomes absolutely awful. But i've got a server with a broadband channel (100MB). The question is: is there some screencast broadcasting software that runs on both win and linux and has multiplexer? I thoug...
I got interested in this after I saw SquareUp use the headphone jack on the iPhone to send credit card data. What's the average bandwidth of the headphone jack on the iPhone, average notebook, and average mobile device? Can it be doubled by sending different data streams on the different channels (left/right)? ...
Hi! For my application, I want to show the user about the network bandwidth. So, that getting delay for downloading will be known by the user.. Is it possible to show them?? ...
I know MBX model has limit of 24MB VRAM. How about SGX models? And can I assume all iPhone/iPod touch models have SGX or MBX at least? No other models? And how much memory bandwidth (to/from GPU) they have? ...
We are using a business Ethernet connection (3Mbit upload, 3Mbit download) and trying to understand issues with our tested bandwidth speeds. When uploading a large file we sustain 340 KB/s; downloading we sustain 340KB/s. However when we run these transfers simultaneously the two transfer speeds rise and fall erratically with a average...
Hi, AppStore reject the online video application due to the bandwidth issue. So i want to check the current available bandwidth for the cellular network and run/download the online video. How can i do this? pl advice.. ...
How do you lower the mimic low bandwidth settings for testing HTML rendering on slow computers? I'm using Safari 4 on a Mac. ...
Hello! I'm trying to test an application that uses a database connection. What I would like to do is throttling the bandwith to, say, 1 MBit or such to get a better feeling for the application under realistic conditions. I already use Wireshark to have a look at the communication with the DB and I expected Wireshark to have a feature l...
The CUDA programming guide states that "Bandwidth is one of the most important gating factors for performance. Almost all changes to code should be made in the context of how they affect bandwidth." It goes on to calculate theoretical bandwidth which is in the order of hundreds of gigabytes per second. I am at a loss as to why ho...
I'm looking into connecting multiple low resolution USB webcams to a single computer. What implications might this have on performance? How does, for example, four 320x240 cameras fare against a single 640x480 camera? I'm not well versed in the architecture of the USB interface, what are the performance caveats? By performance I mean how...
HI, We are developing a multi-tenant application in Asp.Net with separate DB for each tenant, in which one of the requirement is to monitor the bandwidth usage for each tenant, i have tried to search but not found much help on the topic,we want to monitor exactly how much bandwidth is being used for each tenant while each tenant can ha...
I remember someone telling me that gzipped content is not cached on some browsers? is this true? Are there any other reasons why I shouldn't gzip my content (pages, javascript and css files) with htaccess? ...
hey i made a script that uploads files to different servers using php curl and the problem is that it eats all my upload bandwith and my apache does not respond as i would like. the call is made from the php-cli and can not use any apache bandwith limiting bandwith thanks in advance ...
Hi! I develop ASP.NET application on Windows 7 machine (IIS 7.5). I need to limit network bandwidth to test my AJAX GUI. What kind of software could you recommend for those cases: a) I deploy my app to the remote IIS box and try to limit bandwidth of my network connection in Windows 7. b) I deploy my app to the IIS installed on Win7 an...
I want to use mod_rewrite to include a date in an image filename, so browsers will know to refresh an image anytime it's changed, despite any expires headers. My rewrite rule is RewriteRule ^images/[0-9]+/(.*)$ http://my-amazon-bucket.s3.amazonaws.com/$1 which should turn something like http://example.com/images/2010-08-11/example-i...
