Sorry, made things worse.

I first installed WP Performance Score Booster by Dipak Gajjar and my GTMetrix grade went from a D to a B and improved a lot… defer java, css sprites, etc. all improved. Wanting a better score, I first removed WP Performance and installed Speed Booster but my score dropped to a B to an “E” — obviously below what I first had. There are some additional settings for those who are technically savvy and know what and how to enter lines of code from your webpage or from wherever… not sure, so this plugin not good for those who do know anything about hard-coding. So, I deleted Speed Booster, and re-installed WP Performance, and my score went back to you 86% and a B. My “Defer Parsing of Javascript” and “CSS Sprites” are still an F so I need to try and find a plugin that will focus of those issues but both plugins marginally improved those issues – neither “won.”
