How To Optimize Xenforo

XenForo Logo

Xenforo is a very powerful and well-built forum software that is used by thousands of forums all over the internet. Xenforo while fast out of the box does require some work to properly optimize it’s load time for your users. You will need to do a couple of things and this will all depend on your hosting environment.

You will be utilizing the following tools.


You can take these settings straight from a WordPress site and they work well performance wise. The settings from W3TC work perfectly with Xenforo.

Xenforo Caching & Configuration

Performance Tab: Enable the following features.

  • Cache User News Feed
  • Enable Delayed Insert SQL Queries (if you can)
  • Minify CSS
  • Fetch Public Templates As Files (if you have APC, Memcache, or equivalent installed)
  • Cache BB Code Output (set the time to something you deem reasonable)
  • Locally Hosted jquery

CachingThis will vary depending on your server configuration and what you have installed.

All of the below code snippets must be added to your library/config.php file.

Disk Caching: Caching VIA disk is great for static files and content and there is a lot of space and if you are going to cache session information. If you aren’t caching session information and are able to use APC or Memcache do so. Set this for disk caching.

$config[‘cache’][‘enabled’] = true;

$config[‘cache’][‘frontend’] = ‘Core’;

$config[‘cache’][‘frontendOptions’][‘cache_id_prefix’] = ‘xf_’;

$config[‘cache’][‘cacheSessions’] = true;

$config[‘cache’][‘backend’] = ‘File’;

APC Caching: Caching with APC is the equivalent of telling the server to store the information in the servers memory. The advantage to this method is the loading something from memory is much faster than doing so via a file. The down side is that you can run into a cache-slam or cause the server to run out of memory. This should be tested and monitored and you can ask your host for advice. If you are running APC you can also make use of this option in the performance tab in your admin panel which you should do “Fetch Public Templates As Files.”

$config[‘cache’][‘enabled’] = true;

$config[‘cache’][‘frontend’] = ‘Core’;

$config[‘cache’][‘frontendOptions’][‘cache_id_prefix’] = ‘xf_’;

$config[‘cache’][‘backend’] = ‘Apc’;

CloudFlare Settings

Xenforo doesn’t play too nicely with some features of CloudFlare such as the Rocket Loader and you will need to configure it accordingly. You also need to make sure to setup the proper settings to fix the IP addresses of users which you can read about here.

Firewall Settings: 

Security Level: High

Challenge Passage: 30 Minutes

Speed Settings:

Auto Minify: HTML, CSS, JavaScript

Rocket Loader: Off


Caching Level: Standard

Browser Cache Expiration: 4 hours

Always Online: On

Page Rules: 

You need to set the URL of your admin panel ( While you are in here disable everything including caching, security, and performance.


IPv6 Compatability: On


After you have implemented all of these settings there will be a very large increase in your website performance, and you will reduce the load on your server. Remember that you need to do other manual things such as making sure your database is optimized and clean (which Xenforo normally takes care of) and your website should load quickly. This is not the perfect solution
