Performace with scp was around 200KB/s, ftp wavered between 300-500KB/s.
This did not appear to be a duplex mismatch - unmanaged switch showed them
all at 100/Full, put some other hosts on the same ports/cabling and got
near wire speed.
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.
I also did a little more digging and noticed that once I start pinging
from one of these hosts using large packet sizes, I get about 50-60%
packet loss (ie: ping -s 1500 other.vr0.host). If I ping something with a
decent card, I get about 30-50% packet loss. There's no packet loss with
the default packet size.
Anyone else with some vr cards feel like checking this out?
Thanks,
Charles
The first box is running 6.2-PRERELEASE from 11/18, the Intel box is running
7.0-CURRENT from 11/24.

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