The performance bottleneck is usually the DB, and the format hasn't 
really changed since 2.3. That DB format runs tens of thousands of 
queries a second on WP.com, which is usually where we notice performance 
bottlenecks first.

There has always been a built-in object cache that can ease things up on 
your DB, but for the best possible performance I would recommend any of 
the following plugins, including Super Cache written by MU hacker Donncha.

As far as I know all are compatible with 2.5.
