Wicked! That's a good result.
One thing about Google Insights is you probably won't hit 100% (try some of Google's own sites to see what I mean) but it does give you an awesome idea of what you can do to fix things.

Another tool to use which is more comprehensive is Y-Slow: https://developer.yahoo.com/yslow/

Using the two tools together should help you immensely.

Also on your Inspect Tool (Firebug, Chrome Inspect, IE F12…) check out the console. That will show you major errors like missing scripts, images, jquery errors etc…
