Description: ------------ I would like to propose to use clearstatcache() only on writing to cache, as it should occur relatively rarely compared to reads form cache. And since now you flush stat cache on every read, PHP can't use real path stat cache for file_exists and other file operations related to paths. It decreases performance. and the only time anything changes is when you write to cache - create new files, or clean cache so maybe it would be wise to clear it only on write and clean.
