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
vr0: <VIA VT6102 Rhine II 10/100BaseTX> port 0x8000-0x80ff mem 
0xd6000000-0xd60000ff at device 18.0 on pci0
miibus0: <MII bus> on vr0

and

$ dmesg | grep fxp
fxp0: <Intel 82550 Pro/100 Ethernet> port 0xc000-0xc03f mem 
0xdd020000-0xdd020fff,0xdd000000-0xdd01ffff irq 11 at device 1.0 on pci1
miibus0: <MII bus> on fxp0
[...]
fxp0: Microcode loaded, int_delay: 1000 usec  bundle_max: 6
fxp0: Microcode loaded, int_delay: 1000 usec  bundle_max: 6

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


HTH,
Philipp
