Re: How to cripple a postgres server

Hi Stephen,

Are you able to give some detailed technical specs of the hardware
you're running?

I consider yours to be a higher-end PostgreSQL server, and I'd like to
have a good practical understanding of what is required (hardware wise)
to put together a 1k/second transaction PostgreSQL server.

:-)

Regards and best wishes,

Justin Clift
