Admin Panel - Settings > Performance & Caching

For very large social networks, it may be necessary to enable caching to improve performance. If there is a noticeable decrease in performance on your social network, consider enabling caching (or upgrading your hardware). Caching takes some load off the database server by storing commonly retrieved data in temporary files (file-based caching) or memcached (memory-based caching). If you are not familiar with caching, we do not recommend that you change any of these settings.

To find the “Performance & Caching” page, in your Admin panel navigate to Settings > Performance and Caching.

Use Cache?

Select if you would like to enable caching or not. Enabling caching will lower CPU usage and will make pages load faster.

Cache Lifetime

Determine how long the system will keep cached data. A shorter lifetime requires more CPU usage than a longer lifetime. We recommend starting off with 60-120 seconds.

Caching Feature

Select the type of caching you would like to use if you have enabled caching. Memcache caching (if available) will use memory (RAM) which is not as abundant as disk space, however it will be faster than file-based caching when performing read/write operations.

Note: If you would like to use one of the other caching features other than File-based caching (Memcache, APCu, Xcache), this feature will need to be installed on your server and configured to run with PHP before you can select this feature in the Cache Feature list. In addition, you will only be able to smoothly run one caching feature at a time. If you have APCu do not install Memcache or Xcache and visa versa. If you need assistance with installing any of these caching features on your server, your hosting provider should be able to assist you.

Memcache - If you are interested in installing Memcache, you will need to install BOTH the memcache and memcached PHP extensions before you may select this caching feature. For more information, please see the http://memcached.org/ page.

APCu - If you are interested in installing APCu, please see more information about APCu settings in our SocialEngine Performance and Speed Enhancement Tips article.

Xcache - For more information about Xcache, please see their official Xcache page.

File-based Cache Directory

This is where the temporary files containing the cached data are stored. This folder must be writable (chmod 777). This should be a path relative to the base directory where SocialEngine is installed. Select either “File Locking” or “Flush Cache” for the directory.

File Locking? - Selecting “File Locking” disables the editing of any of the contents in this directory by more than one process at the same time. It is recommended that this box be left checked at all times.

Flush cache? - Checking this box before clicking on "Save Changes" would erase all the data in this directory, clearing your current cache.

Translation Performance

Select this option to convert your CSV (comma separated value) language pack files into a PHP array for each language your site is available in. This method is shown to improve response times in server side page rendering.

Note: Certain third party plugins' language packs may not be in the proper syntax to successfully convert into a PHP array. You should receive an alert if any issues arise during the conversion as it may not work if you have third party plugins.

HTML Compression

This compresses all HTML text using GZip compression. It minimizes bandwidth by decreasing the size of the files that are sent from your server. Please make sure that your server supports this feature before enabling it.

Make sure you click the “Save Changes” button seen above when done making any changes on this page.

Note: If you are getting an error involving the "HTTP_ACCEPT_ENCODING" constant. The first thing you should do is disable this feature.

Nice work! Please feel free to contact us if you have any questions or need further tutorials. Visit our community to have more interactions with us and other clients or third party developers. We’d love to see you there!
