The newer kernels perform faster TCP, so you can
ftp/http with more bandwidth. Unfortunately this
can degrade interactive performance when the
remote end doesn't do packet queueing (see CBQ
scheduler & Configure.help for more info).
TCP isn't guaranteed to be fair, and with the new
faster ACKing code interactive performance is more
heavily dependant on the remote end...
