Advanced CSS/JS Aggregation

Last week I created the first RC-1 of AdvAgg. Has a lot of new functionality. Biggest thing if using it is the CDN module requires a patch https://drupal.org/node/1942230.

This week I created the first dev version of Imageinfo Cache. Unlike the D6 version, the D7 version will only focus on image style pre-generation as D7 fixed the performance issue in core. D7 imageinfo cache will generate the presets on file upload just like the D6 version. Comes with drush commands as well.

I'm trying to speed up my website and need some suggestions about what things go together and which typically give you the most performance increase. I need to lower CPU usage and caching seems like the way to go. We really need to decrease CPU because our host (a pretty well respected and expensive VPS) is being overloaded with only 2-3 simultaneous users. I've run Yslow and the developers are working on making the recommended changes there.
