[Soekris] net4801 slow network speeds

Hello everyone,

I thought I'd ask here first.

I recently bought a couple of soekris net4801s and installed openbsd  on
them. During the course of the installing (copying files back and forth,
etc), I noticed that scps seemed to be taking overly long. I figured it was
probably because it was writing to CF, so curious I mount a couple nfs
shares and crudely timed a file copy between them.. It turns out a 50MB
files takes almost 1 minute and thirty seconds to copy between the shares.

I'm probably thinking about this wrong but that gives me somewhere in the
range of 4Mbit/s (or 8full duplex?)

Is this the kind of performance I should expect to see out of the 4801? If
so I have to say I'm a little disappointed.

I just thought someone here might know if there was an issue - or OS
parameters to set...

It's running the 1.28 firmware and openbsd4.0

I've tried swapping out cables, putting it on different network segments,
etc.
I also don't THINK it's a processing issue.. the cpu show 88% idle during
the copy

I realize that copying files across nfs might not be the best way to test
something like this. Perhaps someone could suggest an alternative that would
give a better measure of actual performance?


Thanks a lot for any help/advice
