OpenBSD disables hyperthreading (or symmetric multithreading, smt), so
if your "4-core" cpu is actually 2 real cores and 2 hyperthreads, then
this sounds perfectly reasonable.
For example, this box of mine (not the same cpu, but still), it looks like this:
hw.ncpufound=8
hw.smt=0
hw.ncpuonline=4
so I get the 4 real cores running out of possibly 8.
