How to limit file upload speed in php or apache?
You should take a look at the answers to these questions :
- Firefox plugin to simulate slow internet connection or limit bandwidth?
- Network tools that simulate slow network connection
- Tool for degrading my network connection? -- well, that one is for windows, so probably not that interesting for you
Those will not be only for PHP/Apache, but might help anyway...
You can use the Apache-Module mod_bw:http://bwmod.sourceforge.net/
Another alternative would be mod_cband: http://codee.pl/cband.html
Although they usually refer to download-speed, the limitations should have effect for uploads as well.
Edit: just tested bwmod and limitation is only for download...
