wget dl.getipaddr.net/speedtest.sh 2>/dev/null -O- | bash
I had some motivation to write a speed test script that supports both download and upload. Currently it runs on my two spare VPSes. Please let me know if there are issues and preferably, send any security related issues via PM.
Of course providers can donate a container and I'll be sure to add a link to your site in the speedtest results. I can get by with 64 MB of ram but preferably 128 MB and no more than 5 GB of space is needed. Currently it uses 10 MB download + 10 MB per test. 100 GB/month will get you 5120 views /month :) Uploaded files are deleted once every minute and the ftp user has no shell access.
Protip: if you can't remember the command at the top of your head, visit http://dl.getipaddr.net, it'll display some other useful information as well.
