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. --Chris
