My estimated upload speed is 500kilobits per second. mod_cband seems to do the trick perfectly. I set maximum global upload to 400kilobits per second and all seems to be working well.

Just as a side note for anyone S'ing the FA's, when I ran:

#pkg_add -r mod_cband

it pulled down a version of mod_cband compiled for Apache 2.0, with Apache 2.0 therefore being a dependancy, it was pulled down as well. After I removed 2.0, I needed to reinstall 2.2 and make mod_cband from ports. None of this was a problem, I just thought it should be on the list somewhere.

Many thanks to everybody who responded.
