I just checked with the boxes I have here. One is an Athon XP on a Asus 
board with a VIA Rhine II on board; the other is a `old' Celeron 500 on 
a MSI board with a Intel ``Pro 100/S Desktop Adapter''.
I transfered a 538MiB file (some old CURRENT snapshot) via sftp. My 
result: from box one to box two (vr to fxp) I get 2.3MB/s; from box two 
to box one (fxp to vr) I get 3.1MB/s.

The first box is running 6.2-PRERELEASE from 11/18, the Intel box is 
running 7.0-CURRENT from 11/24.

Output of

$ dmesg | grep vr

$ dmesg | grep fxp

fxp0: Microcode loaded, int_delay: 1000 usec  bundle_max: 6

If needed I can provide a full dmesg of both boxes.
