I read several places that the SAN might be to blame, but
testing with bonnie and dd indicates that the SAN is actually almost
twice as fast as the scsi discs in the old sun server. I've tried
adjusting just about every option in the postgres config file, but
performance remains the same. Any ideas?
As mentioned last week:
Did you actually try to use the local drives for speed testing? It
might be that the SAN introduces latency especially for random access
you don't see on local drives.
