Provides SQLite cache storage that applied before WordPress core load. Doesn't create multiple html files but stores all pages in one file.
On first request to a given URL whole html code of a page is being stored in the SQLite database. On next requests to the same page WordPress core will not be loaded at all but the content of a page will be retrieved from the the SQLite storage therefore duration of PHP execution decreases in dozen of times.
Many sites on the same webserver may use common SQLite storage. Compatible with WordPress Multisite. Requires PHP SQLite PDO.
