I see that eZ Components have a nice support for memcache:
http://ezcomponents.org/docs/api/latest/introduction_Cache.html#memory-caching
So can eZP be configured so that uses this memcache feature? What can be cached in this way? What has to be done in order to achieve this?

Don't know about eZC memcache component, but there's an extension that allows the use of memcache for file locking operations, overriding eZMutex class.

You'll have to rewrite the eZ Publish cache layers (and optimally change them to use one api that uses ezcCache as back end), please send patch :)

Ok, further questions:
- can the eZ Component's memcache functionality be used to cache the query results from the database?
- what about lamemcache (http://projects.ez.no/lamemcache)? What kind of caching does it provide? (besides managing sessions)

Andre, I'm thinking of rewriting the cache layers, could you give me some hints about it...
What cache classes would be best to rewrite?
Is there a single class that I can rewrite which would make memcache work with all caches?

Look at the cluster file handlers, the real meat is in there

And what about adding a new file handler that uses memcache? How does that sound?

I had tried that. The issue is that memcache is not, by design, a persistent/reliable storage backend. It is volatile, and can't really be trusted for persistent data.
Besides that, there is no reason why it wouldn't work.

Yes I see that file handlers don't handle only cache files but also other, persistent files. So I'm back to the previous question:
(but which works only with caching not for other files)
