Thread: Optimizing Advice...Now please

I'm having problem in postgresql performance (response query result)
when installed on
Compaq Proliant ML350 - RAM 256 MB - No Mirror SCSI RAID

I done set postmaster config with [ -B 256 -N 128 -i -o -F -S4096]
Partition "/data" size 3 GB

Any body can advice here....? or request other information to analyze...?

Generally, we'll need schema and query in question.
Also, have you run a vacuum analyze on your data recently?

Yeah, basically table structure , rules, triggers and indexes (probably
just tables and indexes in most cases.
The query and the output from EXPLAIN query is useful (for example if it's
select * from foo; do an EXPLAIN select * from foo;) because it gives info
on what the optimizer thinks is the best plan.
