PHP: Speed Up Your Web Site With MySQL Query Caching

One of the best ways to speed up your web application is to enable query caching in your database, which caches commonly used SQL queries in memory for virtually instant access by the next page that makes the same request. The reason this method is so powerful is that you don’t have to make any changes to your web application, you just have to sacrifice a little bit of memory. This isn’t going to fix all of your problems, but it definitely can’t hurt.
