On the other hand, I tried -1 and 2 settings on an 4 CPU system with a
single hard disk and they made no difference.
How much L2-cache on the cpu(s) was there? Java quite often is larger
than the L2-cache, which then means it's waiting on slower memory.

A setting of -2 on my dual-CPU, high speed RAID array development

Good job!

What would +2 do? Or is the multiplier an absolute value?
0=1
1=1
2=2
3=3
-1=abs(-1)*num-cpus
-2=abs(-2)*num-cpus
-5=abs(-5)*num-cpus
and so on.
