Does the memcache module works by default after instalation (by setting up the $conf['cache_inc'] in the settings.php file ) or it needs some other tweaks or some custom code?

I have memcache up and running on a server and I can see the memcache debug messages. It looks like it is working fine but I can't see any improvements.

I'm using the drupal 6 version on the module.

  • "I can see the memcache debug messages". What are these messages saying? Memcache is quiet, it only writes to watchdog if there are errors.

The memcache module works by default. You don't need to do anything else to get it working. There are some minor tweaks one can do though; here is what my settings.php file looks like: Optimal Settings.php for Pressflow + Varnish + memcache
