way more pageouts

[liv2wrshp]

I used to get 0 page outs on my mbair 11 ultimate with snow leopard. Now on lion dp4, I have 83,000 after a few days.

Lion has a heavier RAM requirement (2GB vs 1GB in SL) and it also seems to be more RAM hungry so it's not a surprise.

Even in DP4 there are still memory leaks.

These bugs will (hopefully) be fixed before the final release in July.

You can launch Activity Monitor and see what apps are using up all the memory.
