More like complaining.  1.6 GHz (the clock rate of Opteron X42s) doesn't go
as far as it used to, and when the CPU-bound app is single-threaded, so
the second CPU can't help, it REALLY drags!  (Of course, the problem
certainly appeared dramatically worse to me than most since I'm used to
the peppy performance of a dual-CPU system under ordinary conditions, and
the dual-cpu /did/ still help there as at least I could continue doing
other things while that bogged, an option a single CPU/core system user
wouldn't have had.  It would and did look bad to others as well tho.  It
was just so /dramatically/ bad for me... I had forgotten what it was like,
and it came out in my complaints on the thread.)

His several year old system might actually be faster than my
several-year-old CPU (it certainly is in clockcycles, 1.8 GHz vs 1.6)
under those conditions.  I was pointing out that mine is admittedly pretty
high class in other areas, but in that one, he /may/ have me beat!

It was certainly part of it.  However, the performance patches added to
0.110 should eliminate the biggest problem.  I haven't actually tested yet
as I just finished first-round processing the 24K of single-part messages
I downloaded the other day, last nite.  It was that 24K messages download
that triggered the thread.

I should get back to testing a small-posts group later this week, but I've
got big-posts groups on the todo list for today.  Until I actually see how
much better the 0.110 patches are, I can't honestly say how much of a
slowdown the other is causing.
