I don't have any ideas to offer on this.

a) I assume you've read /usr/src/UPDATING in your 5.x system,
which explains some settings that you can look at if you
are wondering about performance.
b) the 5.x-series uses gcc 3.3.x for its compiler, while
freebsd-4.x has stayed with gcc 2.94. gcc 3.3.x is
definitely much slower at *compiling* code. If your
only performance measurement is buildworld and buildkernel,
then this difference in compile times is the reason
for most of the slowdown that you're seeing.
