Web perfomance is also very slow while the FTP transfer is running.

50 kilobytes per second translates to 400 kilobits per second, which is 
78% of the advertised upload cap.  Downstream transfers require 
associated upload capacity as well.  If you are maxed out on your upload 
capacity, any downloads will be affected.
