I'm having performance issues also. High load averages on all
postmaster processes. I performed 2 tests:
1) lowered the number of fields/columns from 273 to 60. No affect.
2) changed from adding a new record/row once per second to every other
second. Load average dropped 30-40%
I plan on trying to up the shared memory from 32Meg to 256Meg today.
