OpenBSD Frens...
What's the latest p00p on hw.smt ?
Been doing some looking around and am not able to suss out what the latest guidance is re: hw.smt and performance.
I get the point about security, just wondering if there are any performance "gotchas" with SMT in the kernel nowadays.
I've seen posts (old) talking about enabling smt in the OpenBSD kernel doesn't get great gains. Is this still current thinking/advice?
I remember when FreeBSD SMT was considered "not that performant" but that's not the case any more. Has OpenBSD followed suit?
Inquiring minds and all that...
