I've written some applications than heavily use network, and I would to test it over a slow network. I'm looking for a tool to simulate this kind of connections. Edit: I'm only interested in Windows tools ...
In a Linux-based system (specifically, Ubuntu Server 8.04), how can you measure downstream bandwidth on a per-user basis? Optimally, I would like a method that provides data directly instead of having to run another process and parse its output. I have a technique for measuring per-user upstream bandwidth by setting up one iptables fil...
Is there some way to block access from a referrer using a .htaccess file or similar? My bandwidth is being eaten up by people referred from http://www.dizzler.com which is a flash based site that allows you to browse a library of crawled publicly available mp3s. Edit: Dizzler was still getting in (probably wasn't indicating referrer in ...
I am working on a client proposal and they will need to upgrade their network infrastructure to support hosting an ASP.NET application. Essentially, I need to estimate peak usage for a system with a known quantity of users (currently 250). A simple answer like "you'll need a dedicated T1 line" would probably suffice, but I'd like to have...
What is the best way to reduce the size of the viewstate hidden field in JSF? I have noticed that my view state is approximately 40k this goes down to the client and back to the server on every request and response espically coming to the server this is a significant slowdown for the user. My Environment JSF 1.2, MyFaces, Tomcat, Toma...
I need to simulate a low bandwidth, high latency connection to a server in order to emulate the conditions of a VPN at a remote site. The bandwidth and latency should be tweakable so I can discover the best combination in order to run our software package. ...
Simplified, I have an application where data is intended to flow over the internet between two servers. Ideally, I'd like to test at what point the software ceases to function. At what lowerbound limit (bandwidth, latency, dropped packets) do things stop working to test the reliability of the software. What I thought I would do was the ...
What's a good way to survive abnormally high traffic spikes? My thought is that at some trigger, my website should temporarily switch into a "low bandwidth" mode: switch to basic HTML pages, minimal graphics, disable widgets that might put unnecessary load on the database, and so-on. My thoughts are: Monitor CPU usage Monitor bandwid...
We have a dedicated godaddy server and it seemed to grind to a halt when we had users downloading only 3MB every 2 seconds (this was over about 20 http requests). I want to look into database locking etc. to see if that is a problem - but first I'm curious as to what a dedicated server ought to be able to serve. ...
I'm looking at opening up a website in the near future and aside from the standard domain registration costs, I'm unsure of how to proceed. I'm expecting the volume of data to be quite significant and looking at many webhosts it seems that while they might offer extreme bandwidth caps, I've been told they often suspend accounts before yo...
I need to test a web form that takes a file upload. The filesize in each upload will be about 10 MB. I want to test if the server can handle over 100 simultaneous uploads, and still remain responsive for the rest of the site. Repeated form submissions from our office will be limited by our local DSL line. The server is offsite with high...
What solutions do you have in place for handling bandwidth billing for your vhosts on a shared environment in apache? If you are using log parsing, does your solution scale well when the logs become very very large? Anyone using any sort of module out there for this? ...
I have a client whose desired Web UI is graphically intense; we would like to gather statistics on the average bandwidth of those connecting to the site. Is there an easy way to do that? The "simplest thing that could possibly work" would seem to be a Flash or Silverlight component that times the download of a file of some size (say 200K...
The company I work for is thinking of developing a LAMP SaaS Web application that would be plan based. We want to monitor usage because it involves external references, and would draw bandwidth through the placement of an iframe or JavaScript snippet on a third-party site. My first thought was relying only on a page impression algorithm,...
I am developing a program that continually sends a stream of data in the background and I want to allow the user to set a cap for both upload and download limit. I have read up on the token bucket and leaky bucket alghorhithms, and seemingly the latter seems to fit the description since this is not a matter of maximizing the network ban...
Hey there Does anyone know of a windows build of mod_throttle for Apache 2.2 or lower? Or perhaps another means by which to throttle bandwidth. I need to throttle as low as 64k for a local speed test demonstration Preferably Apache rather than a browser plug-in too. Thanks! ...
I have a client that is paying $1500 per month for hosting of 1 website (1 domain name, email is hosted elsewhere). The website is pretty low traffic. Like, 100 unique visitors a week. The only catch (and why it is so expensive) is that their database is 15 GB, and is replicated from the hosting company to inside my small companies of...
I write web based applications. Performance is obviously a key factor. Whilst database load and page rendering time are things I have control of, the users internet connection is not. What I'm looking for is a way to indicate what sort of a connection a user has. Something along the lines of a traffic light in the corner of a website th...
Is there a Firefox plugin available that will simulate various connection speeds (especially when testing from http://localhost)? I know there are standalone applications to do it, but I'd rather have a plugin. Thanks Edit: Thanks to @UselessAdmin - FirefoxThrottle has now been updated to work on localhost! ...
What is the most bandwidth efficient way to unidirectionally synchronise a list of data from one server to many clients? I have sizeable chunk of data (perhaps 20,000, 50-byte records) which I need to periodically synchronise to a series of clients over the Internet (perhaps 10,000 clients). Records may added, removed or updated only at...
