I searched for this but didn't find a decent answer. My page-ins/outs seem quite excessive. I restarted my machine yesterday and only had azureus on overnight. Today I have 216472 pageins and 136673 pageouts.

I have 384MB Ram and Azureus was only using at most 300MB or so Ram. I often find that I get in excess of millions of page-ins/outs over a few days.

I have also read that the page-outs should be as close to zero as possible and that the system runs more effectively with a static swapfile.

What I find is the main problem after the machine being on a long time is that waking up from my screensaver is slow and also changing to another open application - at least one that uses a lot of ram and hasn't been used for a while.

One thing that annoys me most is the wasted disk space. My swap files go 64MB 128MB 256MB and 512MB and when I quit apps, rarely does it free space until I restart. Is there a reason that small swapfiles aren't used or a dynamically sized single swapfile?

A dynamically sized single swap would allow better freeing of space.

But it would complicate (add bugs) and slow down the VM... both bad ideas. The rule of 2 has proven to be a good memory allocation technique time and again, to the point that it has become nearly axiomatic in CS. People have put a lot of time and thought into this, and not come up with better solutions.
