Basically, instead of uploading at my maximum speed I'd like to be able to set it at say, for example, 10kB/s. This way I can still upload things without having my download speed suffering too much.

Currently using CuteFTP Pro... wondering if any FTP client has this ability though...

i believe smart FTP has a feature like that. Check out the official site at http://www.smartftp.com

Oooooh... and free too.

Thanks! :D
