+1 from me. The overhead of establishing a connection isn't a big deal when you control your own hardware and can route traffic to the database over a gigE backplane, but many of our users don't have that luxury. Routing on AWS seems to be particularly crappy: most of my AWS-hosted sites show a 75-100ms overhead just to establish a connection. That can be as much as 90% of my response time! This fix represents a cheap and easy performance improvement. Let's get it in. Jacob -- You received this message because you are subscribed to the Google Groups "Django developers" group.
