I was comparing the oprofile results of our OLTP workload between
7.5devel and 8.0beta3 test and noticed a new FunctionCall2 in the
8.0beta3 profile that's on the top of the list for PostgreSQL. I
see about an 32% decrease in overall performance. Any suggestions
for determining if FunctionCall2 is really having that kind of an
impact on the test?
Links to results are here:
7.5devel - http://www.osdl.org/projects/dbt2dev/results/dev4-010/128/
8.0beta3 - http://www.osdl.org/projects/dbt2dev/results/dev4-010/180/
Unfortunitely, I lost the database parameters for 7.5devel. :(
