In case anyone cares, this is the same box for which I posted STREAM
test results a while back. The PostgreSQL tests seem to peak on
this 32-core box at 64 clients, while the STREAM test of raw RAM
speed kept increasing up to 128 clients. Overall, though, it's
impressive how close PostgreSQL is now coming to the raw RAM access
speed curve.
