Why does speed matter?
Speed is among the most significant success factors web sites face. In fact, your site’s speed directly affects your income (revenue) — it’s a fact.

A thousandth of a second is not a long time, yet the impact is quite significant. Even if you’re not a large company (or just hope to become one), a loss is still a loss. However, there is a solution to this problem, take advantage.

Search engines like Google, measure and factor in the speed of web sites in their ranking algorithm. When they recommend a site they want to make sure users find what they’re looking for quickly. So in effect you and Google should have the same objective.

How do I find the JS and CSS to optimize (minify) them with this plugin?

Use the “Help” button available on the Minify settings tab. Once open, the tool will look for and populate the CSS and JS files used in each template of the site for the active theme. To then add a file to the minify settings, click the checkbox next to that file. The embed location of JS files can also be specified to improve page render performance. Minify settings for all installed themes can be managed from the tool as well by selecting the theme from the drop down menu. Once done configuring minify settings, click the apply and close button, then save settings in the Minify settings tab.

How do I cache only the home page?

Add /.+ to page cache “Never cache the following pages” option on the page cache settings tab.
