30MB/sec is pretty bad for gigabit if that's the case. I've used netperf
and gotten 70-80MB/sec on my IBM x325s, but I don't have fast enough disks
to really test the system.

Does the switch come into play in this? I've used el-cheapo Netgear
switches and we are looking into geting some demo Foundry swtches to test
out.
