You may be right. I've been fiddling with this, and I noticed that I
got a slight but noticable decrease in speed as I got to ~100% on
cpu1. If I then load it more the speed decreases significantly. At
some point I get cpu2 involved, but that does not seem to get rid of
the speed decrease. Maybe opera doesn't juggle cpus well. Given this,
does that mean a newer box with more cores would not help much?

I tried turning off JavaScript globally when it was fairly heavily
loaded. The results were interesting - both mem and cpu dropped, so
that is a factor. Looks like I need finer grain control of scripts
instead of just on/off...

I added about 60 empty tabs in two more instances. It essentially
didn't change anything. It did start to change if I added sites in the
tabs - each new site access increased mem.

Thanks for the help...
