Make a new file called apc-test.php with inside it the following code:and run it from the browser. Search for the APC block, if you can't find it or it reports as disabled, then I strongly recommend either installing it, or enabling it.PHP:<?=phpinfo();
APC: http://php.net/manual/en/book.apc.php
The Alternative PHP Cache (APC) is recommended by XenForo Limited, and after running XenForo alpha and beta for a while and then turning it on, I can tell you: they are right.The above two points are the main two reasons why I run it.
- Pages load snappy, as if they are run from localhost.
- The server load goes down.
Running vBulletin on the same server showed a load between 0.25 to 0.50.
Running XenForo on the same server (after import) showed a load between 0.15 and 0.35.
Running XenForo with APC on the same server showed a load between 0.05 and 0.15.
I can imagine that bigger sites will benefit even more.
It might be obvious to some, but easily overlooked by others. So I thought it was worth reminding people to consider using APC in order to make the most of their XenForo installation.
And now for the XenForo part Update the library/config.php with these values:Note: The cache_id_prefix is handy if you run more than one instance on the same server. Plus, I still recommend to set one, so it doesn't conflict with whatever else you might be running on the serverPHP:## Caching
