Fine tuning memory consumption

I'm trying to save as much precious RAM space as I can. Currently, after starting KDE, I 200M of used RAM. Is there a way to get a list ordered from processes that take the most memory to process that take the least. I have tried using top, but it reports a lot of things that take up only 0.7% of my RAM. There is a process called kio_http which seems to have 50 instances of itself all taking up 2% (Obviously that isn't possible because that would be over 100%, but you get me point) What should I do?

how much ram do you have? Linux caches disk data in ram, so after a while the ram will look full, but it can take back a lot to reuse. Unless your ram is full AND you're using a lot of swap (256mb), you don't have an issue, so don't worry about it.

Not much point saving memory - why did you pay for it ???.
Does you no good sitting there unused. That is a basic tenet of Linux memory management. Seems to do a pretty good job too.

If you have a real (rather than a preceived) problem let's see some evidence.
Top can be sorted by memory usage rather than CPU% - once invoked use the h (or ?) key. Can also be run in batch so you can pipe it to a disk file for analysis later.

This isn't so much of a problem as it is an investigation. I'm still relavtivel new to linux and I want to know how things work. I have heard of people making super small kernels like Damn Small Linux. I was thinking that it wouldn't hurt to shrink my system down.
