This answer seems a bit vague. Is that the best explanation we have? Do yo= u mean to say that there is not a single freebsd box out there that has a l= oad of less than 0.20?

I'm pretty sure tha= t last time I run FreeBSD that wasn't the case. Also haven't seen t= his load in idle system in any other *BSDs.

Th= anks for taking a look anyway.

Stavros,

Loa= d averages by themselves mean very little.
It's not a fig= ure of cpu usage if that's what you're worried about.
Load averages on BSD are simply processes which have wanted to = run at=20 least once in the most recent 5-second window, with a degradation over=20 time.[1]

Unless you're having a specific problem, I&#= 39;d guess to say there is no problem here at all.

Thanks,

By default `top` doesn'= t show any kernel related processes.=C2=A0 `top -SH`=C2=A0 is useful in thi= s respect and others flags may be useful as well.

= systat -vmstat

^^=C2=A0 Another command that I like.=C2= =A0 Also may give you insight.

Hi,

I just installed 13.1 on a sys= tem, and the load is at 0.20 at all times, although nothing is running and = the CPU is 100% free.

`ps aux` and `top` don't= show anything of interest either.

For what's = worth it, the motherboard is a Supermicro X12STL-IF and the CPU a Xeon 2314.

Any ideas/comma= nds that will help me troubleshoot this further?

T= hanks,
Stavros
