I'm looking for a caching solution for my wordpress network (formerly MU), that has about 30 sites and is growing. My hosting is on a VPS and currently is very slow.
I'm wondering if the newest version is compatible with the 3.5 update (I've had so many issues with other plugins already) and also if it is network compatible and if there is anything special I have to do when installed on the network?
Also, can I network activate it or do I have to do it site by site? Either way is fine, but would like to avoid breaking the sites if possible.
