> it’s also incredibly slow
I never used OpenBSD. Why is it incredibly slow?
Disk I/O is notably slower than e.g. Linux or Windows and executional performance is generally a tiny bit slower, but nothing about it is "incredibly slow".
browsers are exceptionally slow in my experience.
You will want to enable GPU-accelerated rendering for Firefox and Chromium to get a smoother experience when scrolling pages and for certain video playback, because that's disabled by default. Besides that they load and parse pages and act on input pretty much as fast as they do on Linux.
well, SMT/hyper-threading is disabled by default[0] , not sure if there are other reasons though. It's not that bad, but yeah OpenBSD is probably not your optimal gaming OS :P
SMT being disabled is not a reason for anything to be incredibly slow, or even tangibly slower, unless the CPU has a single core.
I left it ultimately because it had way worse battery life than Linux on my T480s and I also wanted to play some games with steam.
