Cool. I've personally tested and used pgsql machines with 128G of
memory and 4 of the AMD 12 core opteron cores and another with 4 of
the newer 10 core Xeons with hyperthreading and gotten good pgbench
and real numbers and real world performance. But that was for
massively parallel operations from thousands of real or simulated
users funnelled through a connection pooler.
Your specific test case will determine the answer to your question.
Do you need to have 1 query exercise 48 cores at once? Or do you need
to have dozens of different processes run quickly?
Are you looking at data warehousing large data sets, a transactional
workload on a relatively small data set? or...
