How can i get better response times?

Does anybody have an idea how I could create a user forum that is as fast and snippy as this one?:

What do I have to focus on? Thanks for your help!

fast server

throw hardware at the problem. No caching for authenticated users.

totalchoicehosting is pretty fast... but doesn't have some of the features i like from the slower providers like dreamhost.

shop around.
