Here’s a plugin you really need to know about if you have a popular site. It’s called WP Super Cache and is the best way to handle a surge of traffic that could bring your servers to their knees. The plugin works by generating a static HTML version of your page, which can be served to a user at a fraction of the machine load of a normal PHP page. When a user hits the site, the page is generated, handed to them and kept in storage in case another user turns up asking for the same page.

It’s pretty useful if you have lots of traffic and can make your website leaner and meaner than any diet pills you know about. Check it out if you’re expecting your site to be popular!
