A couple of weeks ago, OpenBSD announced that they would be disabling Simultaneous Multi Threading (SMT) a.k.a HyperThreading on Intel CPUs over security fears related to side-channel attacks on the cache (much like those of recent Specter fame). Well, I've just updated my OpenBSD 6.3 partition to a -current snapshot that includes the new protection(s) and the results are blog-worthy, so here we go...
