well.... they look all the same to me...
I mean. The load of each ws is about 1, it means the CPU is 100% busy.
If it was less (>1) some CPU-time would be spent in NOOP (No Operation)
it it was more (<1) it would mean that all the CPU is not enough to handle
all the processes without stopping them (the sys, MUST use time-sharing) to
handle all the processes (it is not bad, it means the CPU is busy).
All this applies to a single-CPU ws.
a load of 2.00 on a dual-CPU is (nearly) the same as a load of 1 on a sinle...
and so on.

Of course the CPU (what kind of) is important. An UltraSparc CPU with a load of
4 would be faster than a SS2 with 1 of load!

hmmm... there are some books from o'reilly that could help you...
