lion is a memory hog and awful when it comes to paging in and out to disk, had a client on a 24″ imac that happened to have 2gb of memory, he got away with that memory spec on snow leopard, on lion his machine was practically unuseable directly after the lion install. client angry and frustrated upgrading to 4gb memory the crappy max on this 24″ imac can take … cheers apple, notebook technology in desktop replacement machines ? ADVICE to all out there make sure your mac has 4gb minimum before installing Lion. The amount of memory safari uses is obscene compared to chrome. and the full screen effects are a waste of bandwidth from a remote support perspective. Apple get worse by the month.

tip for anyone suffering in lion with 2gb ram, run the major memory hogging apps in 32 bit mode (tickbox selectable when “command I”-ing on the keyboard the selected application itself) then restart the program
