Oh I definitely will.
Actually it just finished installing and I'm building cvsup right now.
Should I bring it up to -CURRENT first you think?
It's a 5.2.1 disc from maybe a couple months ago.
I'm almost wondering if I shouldn't have tried 4.9-STABLE first.
Is there some kind test I can run to find out if SMP is actually being used
efficiently or not?
John-Mark said something earlier about watching output of "vmstat -w 1" and
if the ID's don't
drop below 20 then I am probably only using a single CPU. Well, I hope
that's not the case
because I ran that while cvsup was compiling (it just finished) and the
ID's never dropped
