Evidently the MacNN Database needs some more RAM, eh?

my computer constantly uses over 1GB in RAM while running toast. if i reset, it goes down to about 200 MB for the system. when running high, it says a kernal_task is taking up over 800MB of RAM....whats the deal? thanks for the help!

DimeTech: do one of two things, either search out one of the many explications of how memory is used in MacOS X (or any unix-based operating system for that matter), or stop looking at any of the memory monitoring utilities... they don't say what you think they say. Memory usage in MacOS X is nothing like the simplistic system use in MacOS 9 and interpreting it like it is will just confuse you.

I could be wrong about this, because it's just what I've heard from others...
Free RAM is not being used at all.
The amount of Inactive RAM is what you should be looking at in terms of how much is available at that time. It's something to do with memory which has been recently used and cached incase it is needed again, but is still available if it's needed.
So, if you only have 5MB of free RAM but 500MB of Inactive RAM then you're doing well.
The Used category is an addition of the Wired + Active + Inactive numbers.
Basically add the Active + Wired numbers to give a closer idea of how much is being used and add the Inactive + Free numbers to show how much is available.

Read this discussion if you want to hear from people who actually know what they're talking about.

Close your eyes. Click your heels together as you say to yourself, "free RAM is wasted RAM, free RAM is wasted RAM, free RAM is wasted RAM". Then just relax and let OS X's memory management do its magic automatically. Open and run as many apps as you like.
