Hi all,

Just added these figures to a new document :

http://techdocs.postgresql.org/techdocs/perftuningfigures.php

As people provide/submit figures and details of the equipment they use,
I'll post them onto this page.

Hopefully it will become a good set of real world guidelines for people,
etc.

Standardised benchmarks would be nice to though.

:-)

Regards and best wishes,

Justin Clift
