Instead of staring at the load readout, see how responsive the box is.
Regardless which OS is installed. A Linux-load of 10-12 isn't normal in my
environment, however we hardly use anything bigger than cost effective
2way boxes. We have a few nntp-servers running cyclone which will spiral
them to death on any RHEL3 release so far but churn along happily with
RHEL4, with a load of 20-50. The box is somewhat laggy at that point but
not too bad.
On our 16-core Sun E2900, a solaris-load of 10 isn't anything to worry
about.
I would say that LA of ~1000 sounds rather insane, on any platform.
