Re: Why openbsd use only 2 of my 4 CPU ?
Thanks Indeed it was very simple, sysctl hw.smt=1 solve the situation. Now my 4 cpu are working all together. I thought this problem was linked to some ACPI related features (like I did on this machine some months ago where I finally find the cause by disabling ichiic) I was on the wrong direction. It's true that those 2 CPU are not "real one", but I feel the difference when using libreoffice.

That *may* be the reason, but the SMT "CPUs" aren't anything like individual CPU cores, various resources are shared. In many circumstances they won't add anything to performance. We have been doing package bulk builds with SMT disabled for a long time: it's significantly faster that way. hw.smt=1 may help at the expense of insufficient isolation between processes. But it might not. The thing causing slowness might be totally unrelated to this.
