I have some initial results using 8.0beta5 with our OLTP workload. Off the bat I see about a 23% improvement in overall throughput. The most significant thing I've noticed was in the oprofile report where FunctionCall2 and hash_seq_search have moved down the profile a bit.
Also, I have libc with symbols now so we can see what it's doing with in the oprofile output. 8.0beta5 results: http://www.osdl.org/projects/dbt2dev/results/dev4-010/199/ throughput: 4076.97 8.0beta4 results: http://www.osdl.org/projects/dbt2dev/results/dev4-010/191/ throughput: 3323.07 Mark ---------------------------(end of broadcast)--------------------------- TIP 8: explain analyze is your friend
