Hello,

I also see in the source code that the default is to enable HT cores: static int hyperthreading_allowed = 1;

So i will test a custom kernel with this disabled.

Well, it's not enough, i still have my 24 CPUs.

I'll give a try to John's way of disabling CPUs, hoping to avoid disabling the wrong ones.

Best regards,

Hubert
