We're not swapping. > Josh, what sort of workload is being tested here --- read-mostly, > write-mostly, a mixture? It's a TPCC-like workload, so heavy single-row updates, and the updates/inserts are what's being measured. For that matter, when I've seen this before it was with heavy-write workloads and we were measuring the number of updates/inserts and not the number of reads. -- Josh Berkus PostgreSQL @ Sun San Francisco ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
