If hyperthreading is definitely NOT an issue, it will save me a trip to the co-lo facility.
Thanks,

This is driving me crazy. A new server, virtually identical to an old one, has 50% of the performance with pgbench. I've checked everything I can think of.
The setups (call the servers "old" and "new"):
old: 2 x 4-core Intel Xeon E5620
new: 4 x 4-core Intel Xeon E5606
Actually it's not 16 cores. It's 8 cores, hyperthreaded. Hyperthreading is disabled on the old system.
Is that enough to make this radical difference? (The server is at a co-location site, so I have to go down there to boot into the BIOS and disable hyperthreading.)
