Aha! That's why... I've seen the '500' in some dbt2 samples and thought
it'd be a good default value.
But it makes sense that the benchmark doesn't automatically 'scale down'...
Stupid me.
Thanks again! Hoping for larger NOTPMs.
Yeah, I ran with 500+ warehouses, but I had 6 14-disk arrays of 15K
RPM scsi drives and 6 dual-channel controllers... :)
