so far, it looks promising (using the first example command I found in the
[root at iLab1 1]# done/netperf-2.1pl3/netperf -H 192.168.0.200 -t UDP_STREAM
-- -m 1024

I get 94 Mbps for a single (unbonded) channel (same as I saw posted at
netperf.org before buying the rtl8139 cards). Note that this test did
crash the rtl8139 driver shipped with MDK-7.2beta3 (kernel 2.2.17). But
it worked with the 8139too driver. I'll try to see if I can pull out some
info from the crash and send a bug report.
I'll try other tests and other packet sizes, etc. With a bit of tuning it
looks like this could really be very nice. Combined with PVFS and other
tools, I think that I am going to like this cluster!
