LMCE using too much memory

[donpaul]

My LMCE core regularly uses over 3G of my memory, and I often need to reboot. LMCE is using 1G the minute it boots, and will stay there until I start doing something. When watching live tv, memory always maxes out. From what I read on here, that shouldn't happen. I am tempted to reinstall and start over, but I'd rather not go through that again. Also, would be nice to have a highmem kernel Memory is cheap, and 8G would be easy.

nonsense! that's not what these numbers say at all. do some searches on memory use in the forum and you'll get your answer very quickly... a core can very comfortably run on 1G RAM and at a push even 512MB without too much difficulty. if you want to confirm this, just check how much swap space it is using... you'll see its almost none at all (30MB).

You're right. I didn't take into account the disk cache. Brain fart...
