Firefox Page Speed shows no performance increase

[Meini]

Quick Cache Plugin is installed and working according to the report at the bottom of the source page. But when I test the performance with Firefox/Google Page Speed I get 84/100 regardless whether the plugin is enabled or not.

How come?

Quick Cache tunes your Page Rendering speed, not Browser Rendering Speed.

In other words, Quick Cache gives you a huge speed improvement, because it dramatically reduces the overhead that your server has in rendering database-driven content. However, the game does not stop there. Once a page is rendered to a browser, there are things like style sheets ( CSS files ), images, overall text content ( your code ), JavaScript libraries, etc.

I suggest this article, which will take you into the next phase of optimization:
