Memory Issue?
Hi:- I am relatively new to linux and especially to SuSe.
Users are complaining about poor performance on a server. CPU seems to be okay. It seems like it's using a fair amount of memory - but there doesn't appear to be anything that's hogging the memory.

Is there an easy way to find out what is eating up the memory?
Thanks
