Why openbsd use only 2 of my 4 CPU ?

vincent delft-2
Hello,

I've migrated to -current to test the auto-join, but since then, my system
is slow. Specially with libreoffice, firefox, ...

By looking at top, I've saw that only 2 CPU are actually running.

(Should I say that with OpenBSD-6.3 this was not the case.)

What can I do ?
In which direction could I search for a solution ?

The dmesg and Top are here after.

regards

In the name of security, hyperthreading has been turned off in -current.

SMT was disabled in current about a month ago for speculative security
reasons. You can turn it back on using the sysctl hw.smt.  Refer to the
commit message for revision 1.178 of src/sys/sys/sysctl.h for more
details and rationale.

Your CPU has 2 cores. With SMT (HyperTheading), it appears to have
4, but SMT was disabled in -current for security.

You only have 2 real cpus.

the others are HT, and we disable those due to a security hole
called tlbleed.

You can search for the rest of the information yourself.

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.

Re: Why openbsd use only 2 of my 4 CPU ?

In reply to this post by vincent delft-2
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.
