i have tried searching, couldn't find specific scenario.
have noticed when use mpb on course of school week, when check activity monitor, ram usage goes 1.36gb (from startup) 3.60gb (at end of week or few days later).
know supposed happen when using programs , leaving them open, in case, close out of before go sleep. no safari, no itunes, nothing , ram usage still extremely high.
solution have found restart , down goes again 1.36gb. notice no difference in performance, curious if common or supposed happen...
thank you.
take @ inactive ram , read link below better understand ram. doesn't matter how of ram used. matters if you're exceeding ram capacity , paging.
determine if can benefit more ram, launch activity monitor , click system memory tab @ bottom check page outs. page outs cumulative since last restart, best way check restart computer , track page outs under normal workload (the apps, browser pages , documents have open). if page outs significant (say 1gb or more) under normal use, may benefit more ram. if page outs 0 or low during normal use, won't see performance improvement adding ram.
