P5 Speaker Series - Thursday April 9, 7:00 pm

For those who are interested in the OLTP oriented presentation with
PostgreSQL, the next presentation will cover how to test your system
to determine expected disk performance from various Linux filesystems
and RAID configurations:

PostgreSQL Portland Performance Practice Project (P5)
A series of presentations by
Mark Wong

Sponsored by the Computer Science Department, Portland State University

This series will consist of 5 to 6 presentations aimed at PostgreSQL
database users who wish to learn more about tuning their systems for
performance. Attendees will learn how to generate and interpret
operating system (Linux) and database statistics, and the effects of
some system tuning techniques.

This involves studying the well known Online Transaction Processing
(OLTP) benchmark called TPC-C ( www.tpc.org ). TPC-C was developed by
a committee, representing all major players in the database
marketplace, to be representative of typical online enterprise
databases.

TPC-C consists of a precisely defined schema and 19 queries. We will
review the schema and queries and demonstrate how each tuning
technique affects their performance. We will use an open source
package that the speaker has developed, called DBT-2, which many DBAs
have found useful.

Mark Wong has an MS in Computer Science from OGI and several years of
experience developing and executing various database systems
benchmarks. Most relevant to this series are his years spent at the
OSDL developing and using a fair-use derivative of the TPC-C benchmark
to characterize system performance of open source software. He now
works at HP StorageWorks on their NAS products.
