Probably, but not with me :-) The foundation work for SMP has been done, and a couple of FreeBSD boxes have successfully run multi-user setups with the SMP code enabled, but it requires a lot more work before it'll be integrated into the FreeBSD source tree and made generally available. (Basically the kernel locking systems need to be refined. I believe that there is (or was) one big lock on the entire kernel, so only one processor could be in the kernel at once. That needs to be refined down to much finer grained locks before it'll be truly useful). Gary
