First of all you are going to have to show use what these queries are
exactly, what the machine is you are running on (CPU, memory, and
disk) , and how you have tuned it.
slow is a relative term.. we need information to determine what
"slow" means.

Hi
I am trying to run sql-bench against PostgreSQL 8.1.4 on Linux.
Some of the insert tests seems to be ver slow
For example: select_join_in
Are there any tuning parameters that can be changed to speed these
queries? Or are these queries
especially tuned to show MySQL's stgrenths?
