I'm testing this plugin with other plugins but they don't seem to work when activated:
2. Force gzip: Implements gzip output compression to speed up load times. This plugin also does a check to see if browsers are incorrectly saying that they do not support GZIP when they actually do. This can speed up load times for a significant portion of users.
Also, when I look at the cache folder in the wp-content folder, I don't see any of the pages being cached. Shouldn't there be an individual html file for each page that is being cached? When I look into the bottom of the source code of the html I can see the message:
<!-- WP Fastest Cache file was created in 1.1710290908813 seconds, on 26-10-13 22:40:29 -->
