Install
No release zip yet. The repository archive installs, but the folder name will carry the branch suffix and updates will not flow:
wp plugin install https://github.com/pressjitsu/pomodoro/archive/refs/heads/master.zipReadme
WordPress Translation Cache
The WordPress gettext implementation is very slow. It uses objects that cannot be cached into memory without reinstanting them.
pomodoro stores all seen translations as a PHP hashtable (array), that can be subsequently stored into a file as PHP code and levereged via OPcache when loaded.
Moreover, pomodoro does lazyloading for strings that are only encountered in output. It does not preload everything it can for a domain until there's no other choice.
But does it really work?
We think so :)
Example on a vanilla ru_RU locale WordPress site:

Installation
Drop pomodoro.php into wp-content/mu-plugins and enjoy the added speed :)
The more plugins you have the better the performance gains.
You can use POMODORO_CACHE_DIR constant to change cache directory (needs full path).
