[Soekris] Throughput for various models?

[Bill Borton]

I picked up a couple of net4501s for use as time servers and am pretty darn
impressed with them.  I'd like to get a couple more and use them as simple
router/firewalls running NanoBSD.  A quick throughput test with iperf only
gives me ~14 Mbits/s without fastforwarding and ~39 Mbits/s with. (~94 
Mbits/s through just the switch.)

Do these numbers look correct for a net4501?  Can anyone give me some idea as
to what to expect with other models?  I'm thinking about the 4801 and 5501.

If my numbers *don't* look right, can anyone give me some pointers as to where
I may have gone wrong?  I'm new to FreeBSD/NanoBSD but not to *NIXs in general.

Thanks guys.
