Please try IronCache — a memcached extension for ExpressionEngine
Once in a while at Grist we write some software that we think might be useful to people other than ourselves. Sadly, we rarely have time to clean up and/or release these bits of code — there are few of us, and generally a lot to do. That said, we’ve been able to make a happy exception in the case of IronCache.
IronCache is an extension for the ExpressionEngine CMS that boosts performance for high traffic sites by using memcached, the world’s most popular general-purpose memory caching system. We’ve been using it here at Grist for about 18 months on our EE 1.x-based site. We’ve ported it to EE2, and are now releasing it.
