On my similar Dell/linux 2.0.34 box we get speeds about 5-8 MB/sec
And after switching from NT we don't even use the second processor,
the reason being that the linux driver had some compatibility problems
with
dells onboard 3com card in SMP mode.
I'll revisit the dual-processor issule once linux 2.2 final is out.
from your numbers it looks like you are not using IP on your Solaris
server.
