Unfortunately without -S, you're not really testing the processors. A
regular pgbench can fluctuate a more than that due to writing and
checkpoints.
For what it's worth, our X5675's perform about 40-50% better with HT
enabled. Not the 2x you might expect by doubling the amount of
"processors", but it definitely didn't make things worse.
