I had never problems with FreeBSD 3.4 and 4.1-stable running on my dual PII box -
performed very well, even with a large load, which bloated my linux-2.2 - linux-2.4 is
much better, but the SMP code of freebsd 4-branch is definatevly faster than linux-2.4 in
my experience around 5% - so you have to benchmark a lot to see the differences :-) - My
box never hung with high load nor with low ... And I had it running for some time now ...
