I assume you've got 512 MB installed and you're saying 300+ MB is in use with no applications open, about 200 MB free.

Yes

If this is after a long amount of usage without logging out or rebooting this is caused by memory leaks (bugs) in applications that are allocating memory blocks and then not releasing them back to the kernel when the application is closed. If you log out (quicker than rebooting) you should be back to normal, if not, you'll need to reboot.

I'll try this. Thank you.

I'm not sure about the Mini, but most of my Macs using Tiger are about 160-170 MB in use initially after reboot

Yes, that is my experience.

and gradually leak upward to where a large proportion is used, but the leaked memory is actually "lost" so it isn't really in use, it's just like it's not even there. A good reason for anyone to use MenuMeters simply to be sure their system hasn't bogged down from memory leakage.

Is there a limit to this? Or would all one's RAM eventually "leak".

Aside from a kind of inherent reluctance to change,
I sort of pine for the greater simplicity of earlier OS versions.
But, the world moves on.

Aside from memory leaks I think OS X's memory management is pretty good. One trick that can speed things up some is to have a dedicated partition for the virtual memory swap volume. You can read about advantages here: http://www.bombich.com/mactips/swap.html There are utilities like SwapCop, SwapSwapVM, and Swap Relocater that can do this for you without resorting to Terminal commands. See: http://tinyurl.com/chvuw

I'll look into this.
Thank you Kris.
