> Postgres won't use more than 1 CPU core.One *connection* to PostgreSQL won't directly use more than one
core. As Merlin suggests, perhaps you're really only running one
query at a time? The other possibility is that you're somehow
acquiring locks which cause one process to block others.
The "one connection" theory appears correct per prior email, if correctly understood what I was reading.
I guess I need to head back over to the Npgsql folks and see what I am doing wrong?

Most benchmarks I've seen comparing hyper-threading show that
PostgreSQL performs better if you don't try to convince it that one
core is actually two different cores. With HT on, you tend to see
context switching storms, and performance suffers.
You really shouldn't let the marketers get to you like that. You

have four cores, not eight.
I agree. :-) Just trying to express things as my OS sees and reports on them.
