Subject:   Load at 1.00 on SMP machine 
Message-ID:  <OF9ACCB411.F4F2A39D-ONC12570C0.00391AC1-C12570C0.00391AC5@suedfac.com>

Hi,

i got a Problem on my dual XEON 3.06 GhZ machine, 2GB of RAM, FreeBSD
5.4-STABLE.
I got "option SMP" in the kernel config and "machdep.hlt_logical_cpus=1" in
/boot/loader.conf.
There are just 20 processes running (typical ones like getty and stuff) and
the load of this machine is at 1.xx. There is no bgfsck and other stuff.

So, i built a new kernel without "option SMP", rebooted, and the load was
at 0.0x. But only one CPU was used (detected).

So, what could bei the Problem?
Well, the machine shows me 4 CPUs, HTT is not enabled via /boot/loader.conf
and "machdep.hyperthreading_allowed". So, how to disable HTT? Maybe this is
the problem of the high load?

Thanks in advance.
