sysctl hw.ncpu
if it says hw.ncpu=3D1, you're only using 1 CPU.
You need to get a SMP kernel and put it in place of the standard
kernel. Or better yet, build one as per the guide.
There aren't any good english language books on NetBSD that I know of.
But a guy named Michael W. Lucas has written good ones on FreeBSD and
OpenBSD. Every time he shows up I make it a point to bug him about
doing a NetBSD book.
