file cache performance

The way CI works is that it checks early on if a valid cache file exists for the requested URL and if so, loads that one file and exits without loading the controller/model/libraries/helpers/views/etc files. No queries to the database, no php processing of whatever your controllers and models are doing or anything else. Just loading a single post-php processed html file. That will always be faster and more efficient.
