Well, that's the usual reason. Depending on what you're trying to find
out, you might check the *stat utilities (vmstat, iostat, systat, and
possibly a few more) and things in /usr/ports/sysutils (I use
gkrellm).

Well, that looks right to me. The only thing I can think of is that
the buildkernel might have failed in a non-obvious way (I've had that
happen), so you wind up installing the old kernel. Do a "uname -a" and
check the build date on the kernel.
