I had a similar experience. regardless of scaling, etc, I got same results. almost like flags are not active.

did pgbench -I template1 and pgbench -c 10 -t 50 -v -d 1 and played around from there.... This is on IBM pSeries, AIX5.3, PG8.0.2 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of William Yu Sent: Tuesday, June 21, 2005 12:05 PM To: pgsql-performance@postgresql.org Subject: [PERFORM] Trying to figure out pgbench My Dual Core Opteron server came in last week. I tried to do some benchmarks with pgbench to get some numbers on the difference between 1x1 -> 2x1 -> 2x2 but no matter what I did, I kept getting the same TPS on all systems. Any hints on what the pgbench parameters I should be using? In terms of production use, it definitely can handle more load. Previously, Apache/Perl had to run on a separate server to avoid a ~50% penalty. Now, the numbers are +15% performance even with Apache/Perl running on the same box as PostgreSQL. How much more load of course is what I'd like to quantify. ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
