On my system (dual PIII 550) I usually do make -j8 buildworld without
any problem. For kernel, any value greater than 3 fails, so I usually do
a make -j3 buildkernel. For ports I don't use -j at all.
Your builworld should work with -j2 or 4, I've run -j3 on a single K6-2
box without problems too.
What kind of disks does that machine have? buildworld is pretty io
intensive, having fast disks makes quite a difference.
Cheers,
