The next round of Intel Xeon chips have core-counts in tens. UltraSPARC Niagara (T1, T2, et alia) have had lots of cores for quite some years. Multicore ARMs are in all mid-to-high-end smartphones & tablet computers.

Can the NetBSD kernel use them all efficiently & effectively?

Have the user land applications which can be parallelized been parallelized?

What is the current status of NetBSD SMP system support? Which kernel subsystems still need work, and which are done?

Bit late reply, but we have had support for upto 256 CPUs for ages now.

I don't know much about userland though.
