I've recently gotten access to some Apple Xserves running OS X 10.6.5. They

When I run mesa star with OMP_NUM_THREADS=4, I get performance that varies
between 100% and 150% of 1 CPU, whereas I would expect it to be above 300%
most of the time (I/O is not the cause). top tells me that Spotlight
(mdworker and mds) are running pretty heavily in the background.
