xcache/apc,... are opcode caches
memcached (and apc as seen in this presentation, didn't know this^^) are object caches
Check the link for more infos

Yes please, but how can I contact you - I can't get memcache to install and the extention to load?
On my SSH it says this "Package(s) memcached available, but not installed."

PC whats that is it person conversation, wont other people be able to see it?
Other people won't be able to see it. Basically, I'll need to login to your server, with your permissions and see what's going on, such that you aren't able to execute php with flag i.

I am using file system caching, and I'm not really noticing a reduce in memory usage... Particularly, I am seeing similar memory usage, 1 less query on home page, and same queries on at least forum display, show thread, as well as new reply.
I wonder if the cache are being made use of to their fullest potentials yet, or if Kier and Mike will be adding more uses on them?

Following up on this, I am noticing / suspecting the File cache is not being hit as frequently as it should be. A LOT more code digging and tracing will need to be done to find out what exactly is happening. I suspect File cache is not being hit properly because after enabling File cache, and installing APC, I am NOT seeing the File cache entries showing up in apc.php under System Cache Entries. Modifying the config.php file to use APC backend cache and it seems to be working as intended. I am seeing the xf entries in apc.php under User Cache Entries. I am also noticing memory usage about halved, as well as a significantly faster load time. Switching it back to File cache does not introduce files in the APC System Cache Entries either.

Memcached is not efficient on a single server setup, it is a distributed system. Use an opcode cache instead.

This is question for the optimization experts, even though I suspect my google reading have probably gave me similar answers already...
On my dev test bed installations on different servers, I am noticing a lot of fragmentation on the APC cache even though it is not being used anywhere near its limit (shm_limit="32m", usage only around 10m). Should I worry about this, or is it safe to ignore?
