DBT-2 results using tablespaces
Hello,
Just wanted to share some data I've generated with dbt-2 using
tablespaces from a CVS export of PostgreSQL on June 22. I have results
and details on how I have the disks laid out with LVM2 here:
http://www.osdl.org/projects/dbt2dev/results/dev4-006/538/
The performance appears to be on par with results I've been getting with
PostgreSQL 7.4.1. For a comparison, you can see those results here:
http://www.osdl.org/projects/dbt2dev/results/dev4-006/526/
The volume where the database log resides is identicle between the two
tests. The disk layout has only changed for where the tables and
indexes reside.

Your response times improved across the board over 7.4.1.. Is that
change significant, or within the variation you see on your system?
