I thought I could use a 2 x 400MHz Ultra Enterprise E250 with a new Sun GbE card in it as a killer client, and I find that with V3 32KB UDP packets, the sucker rolls over at ~30 MB/s
Count yourself lucky, I was trying to size up a large network of linux boxes all talking to a couple of netapps but gave up when I discovered how pants the linux network client it. I even offered cash for one of the kernel hackers to work on the client rather than the server and still had no offers. For our workload we can't even get 1mb/s with a linux box... Back to your problems though. The fact that both gbe and 100bt both peg out looks like it may be some sort of bus or stack problem. Are your network cards PCI 64/66? If they're only in 32bit 33MHz slots I could quite believe a 30MB/s limit. It could also be that the sun is set up with too few nfs threads or something like that.
