You're right, it sucks to have a network stack that's not
multithreaded on the other hand it's really nice that everything works
(ignoring the SMP related issues) on the other hand freebsd supports
all those cores & puts them to use, but the hardware support is not
there, for me featureset is far more important than performance but I
guess if you're dealing with 10 or 20Gbps speeds it's the other way
Is it right to forefit technical correctness in pursuit of speed?
