-- memcache A client for the memcached server, which caches database
- information in volatile memory. This is important for
- adequate performance on high-traffic sites. You will
- also need a memcached server to store the data in.
+- opcache Improves performance a _lot_. Included in PHP, must be
+ enabled manually in php.ini for most distributions. Find
+ and set at least: opcache.enable=1
- mailparse Efficient parsing of email requires this extension.
Submission by email or SMS-over-email uses this.
- sphinx A client for the sphinx server, an alternative to MySQL
will be emulated if not present.
- exif For thumbnails to be properly oriented.
-You may also experience better performance from your site if you install
-a PHP bytecode cache/accelerator. Currently the recommended cache module
-is 'xcache', which after installation (php5-xcache) can be enabled in
-your site's config.php with:
-
- addPlugin('XCache');
+You may also experience better performance from your site if you configure
