Installed and re-tested my site on GTMetrix.Boosted from a C to an A on PageScore. This plugin worked on my simple portfolio website, but my other site that I run a news publication on had the opposite effect. It actually made that site worse. Went from a C+ to an E. This plugin could be the simple fix for your site, I highly recommend trying it!

Great plugin. Checked site on GTmetrix and had a score of 0. Uploaded the plugin and checked again and the score was 87! Results speak for themselves.
