I've got a Macbook Pro C2D, with 3GB RAM, running OS X 10.5.2. Long story short, I've got about 800MB of inactive memory, and still it's swapping like crazy, throwing 20 second freezes into my typing, etc. Unusable. But why is it swapping, when there is so much memory available? I just don't get it. Isn't inactive memory by definition easy to free? If so, why isn't it taking advantage of it, instead of acting as if I'm actually *using* the whole 3 gigs? I recently upgraded from 2GB to 3GB to be able to use VMware Fusion better. Well, I can't. Despite adding 1024MB of memory, I couldn't even increase the VM from 512 to 768MB. Where did the rest of my new gigabyte go? I can't say it feels any faster at all. As of right now, I've got about 1.65GB active memory, 520MB wired, and over 800MB inactive. Despite all that inactive memory, I've got over 500MB of page outs! I don't pretend to understand paging very much at all, except I do know that excessive paging (as in 500MB in 10 minutes) feels EXTREMELY slow. Is this by design, and if so, why...? If not, well, why does it happen? :) This email sent to site_archiver@lists.apple.com
