Our performance on XP > is not great. Also, which version of PostgreSQL are you using? That actually depends a lot on *how* you use it. I've seen pg-on-windows deployments that come within a few percent of the linux performance. I've also seen those that are absolutely horrible compared. One sure way to kill the performance is to do a lot of small connections. Using persistent connection is even more important on Windows than it is on Unix. It could easily explain a difference like this. //Magnus
