Re: Performance Benchmarking for data-warehousing instance?

I used PostgreSQL 8.4 for Pentaho OLAP (mondrian) for a while. It's work
like i want. But all i've done are the combination of Application level,
Database level and Hardware level.

Our application is CRM, Then we did ETL to new PostgreSQL server, and do
OLAP there. The application and OLAP DBMS is totally difference
configuration. In Hardware level with hardware optimization and
postgresql.conf configuration. We can run OLAP query for our need.

I think you have to know your database behavior and what OLAP you need to
query. Then you will know how to configure your OLAP and postgresql.conf
and Hardware you need.

Benchmark tool is only a test. But you have to know all about pg_log and
performance monitoring.
