nothing about your performance, the multi-core system will perform

the only time you care at all about performance.
I think some information is getting lost here. I'm not comparing
single vs multi core operation in a purely mathematical sense on
identical hardware. I'm trying to decide between a setup that uses a
relatively fast single core vs a setup that uses slower multi cores.
In aggregate the multiple cores have more processing power than the
fast single, but in isolation are notably slower. The workload is
mainly pf, and given that pf is currently single threaded, I'm trying
to figure out if the other stuff on the box causes enough overhead
that going with slower multi cores will end up being faster in the end
or not.
I red all thoughts till now and my advice is if you are going to buy
a new hardware now (year 2015) take multi core CPU.
The OpenBSD just get better every day and if you follow tech@,
source-changes@
and misc@ you already know that our beloved OS soon or later will
spread load
on all CPU/CORES (device drivers, TCP/IP stack, pf and so on).
