The PhpFastCache module makes use of PhpFastCache library. It's main goal is to improve Drupal's performances by adding a new cache backend system depending your needs

• phpfastcache/phpfastcache
• php7

1. Enable PhpFastCache module in:
   admin/modules

2. You'll now find a PhpFastCache tab in the "Configuration > Development" menu
   admin/config/development/phpfastcache

3. Settings up the driver you need and it's options (if needed)

4. Alter your settings.php to add this line:\

$settings['cache']['default'] = 'cache.backend.phpfastcache';

Plenty ATM, but it's still in development :)
