I've done a better controlled series of tests where I restore the database before each test and have grabbed sar and oprofile data:
http://developer.osdl.org/markw/dbt2-pgsql/176/ - load of 100 warehouses - metric 1234.52 http://developer.osdl.org/markw/dbt2-pgsql/177/ - load of 120 warehouses - metric 1259.43 http://developer.osdl.org/markw/dbt2-pgsql/178/ - load of 140 warehouses - metric 1244.33 For the most part our primary metric, and the vmstat and sar output look fairly close for each run. Here are a couple of things that I've found to be considerably different from run 176 to 178: - oprofile says postgresql calls to SearchCatCache increased ~ 20% - readprofile says there are 50% more calls in the linux kernel to do_signaction (in kernel/signal.c) Would these two things offer any insight to what might be throttling the throughput?
