I've been looking for a speedtest platform for centos around the web without much success unless I want to spend $900-$2000. I run a small voip company network that host a few friends etc. Some people have crapy internet connection to my server in town. The best way to test it is to have them either ping or do a route trace. Well some of these people are not computer savvy. What I'm looking for is something that I can install on my centos server so that people can go to a website on it and get their speed/jitter/packet loss etc. Any suggestions?
