I am also trying to get a quad-Opteron versus the latest quad-XEON from

15k vs 30k is indeed a big difference. But also realize that Postgres has a specific benefit to Opterons versus Xeons. The context switching storm happens less on an Opteron for some reason.

I would venture a much greater benefit than 5-8%, more like 10-50%.
