OpenX memcached configuration

Configuring OpenX memcached will help you significantly speed up your banner delivery and i recommend you to use it instead of the default file File based cache.

OpenX memcached configuration from Web Interface

This tutorial has been made with openx 2.8.10 but should work on most of the 2.8.x installations.


First you need to go to plugin section and configure memcached servers. This can be tricky since there is no direct access from the web interface.

You need to change the end of the url with:  /plugin-settings.php?group=oxMemcached ( for default installation you should get )

Add your memcached server and port if it’s default installation on the same machine add localhost:11211 and expiry time of 600 seconds.

You can also use memcached with multiple instances.
