I think that your performance question is moot, because here on linux
(Debian Squeeze, amd64) with 9000 concurrent users unbound eats approx.
5-6% CPU at peak time at lower-spec hardware. The CPU is Intel(R)
Pentium(R) Dual  CPU  E2200  @ 2.20GHz (two cores, each has 4399.60
bogomips), the server has 2 GB of RAM.

As for stability, I can't really judge, but we had no crashes yet.
