Since upgrade system is using a LOT of memory

[ViperDesign]

I have 4GB installed in my system. I NEVER had gone below a gig with firefox, aperture, ps and LR opened at the same time , but with leopard I am down to around 40mb available! It seems to use a LOT more ram to open programs. I mean if I just open LR and PS3 with Firefox open I am down near 1gb.

Anyone else having these issues? I mean I can't add more ram! lol

I have 187,000 page ins and 184,000 page outs.

What is going on?

yes, I have noticed the same thing. I leave activity monitor open in the dock with the pie graph of memory usage, and even with every app closed and such, I am getting a ton more page in/outs and its leaving "active memory" open even when no apps are open.

Totally different from tiger. Not sure if it's hurting performance, but that pie graph I am so used to seeing in Tiger is now showing alot more memory usage.

My first guess is that Leopard is better at memory management and therefore it uses all the memory it can.
