I've set up Memcached on our server, given it a lot of memory to use (4gb), and changed all the settings in UNA (pointed to localhost at port 11211). But I'm really not seeing a big difference in peformance. We've had a big increase in users in the last few days, and I don't see more memory being used on our server, but I do see a LOT of extra disk usage. I wonder if it's not using Memcached. Does anyone know how to tell or know of anything I might need to check?
I can connect via telnet to that port on localhost, check Memcached status, and see it has connections to it, so I feel like something is happening. Thanks for any help on this!
