FreeBSD Maximum CPU/RAM

[Tan Heng Chai]

I saw a couple of threads on people running FreeBSD on 8-way Xeons,
seems favourable though.

Not meaning to be "rude" (this is after all, a FreeBSD mailing list),
but is there any other OS that scales CPUs, minus Solaris? I have just
chucked Solaris 9 out of my box after 1 week of experimenting. Way too
painful to tune to.
