Check your cabling... you may have a bad pair in your cable on your
send wires, or at least a crummy pair with high resistance. See if
netstat -i has any errors listed. A change in performance that
dramatic and only in one direction is disturbing and doesn't sound
like a kernel or software issue, though I could be quite wrong.
