Just to be sure it handled a light (for it) workload, I verified that
highpmd-2.6.9 successfully runs OAST with 6000 users on an 8x P-IV HP
Proliant with 32GB RAM. The stress test completed successfully. The
2.6.7 version completed runs with as many as 10000 users off fresh boots.

Some performance measurements came out of it, of course, but these
are not particularly meaningful without baselines and the like.
Rather, these results are only meant to indicate a stability level.
