Upon inspection using xhProf, I realized that the PHP implementation loading the MO files is really slow. From my tests, about 25% to 40% of the time WordPress spends rendering the page is actually spent locating, parsing and merging all the translation files.

This plugin works by caching the whole $l10n variable holding all the text domains and overridding the load_textdomain.

Caching is done using serialize and written to wp-content/uploads/l10n.pson. Be sure to regenerate the cache if a .mo changes.
