RokBooster
RokBooster uses a combination of libraries, parserers, compressors, caching and background processing to increase page loads speeds dramatically. Some of the libraries I used include; JSMin, YUI, phpQuery, and LESS.
Background processing of caching and compression on the first call to a uncached page, the page itself loads normally, this prevents the typical bogging down when a page is initially called and pages that haven’t been called will also not take up server space.
MD5 sums on compressed and cached files ensures that any changes to a page will automatically trigger the re-caching of it.
PhpQuery for DOM parsing is used in place of traditional Regex, which is much faster and uses less resources.
YUI does not account for @import stylesheets, so LESS aggregator is used to retrieve and compress these files that would normally not be included in caching.
AJAX is used in the administration to quickly clear all cached files.
