    Hi guys.

    I've been recently dealing with this problem(?).
    I had little trouble with my 16GB RAM so I am currently using 8GB.

    After heavy RAM usage such as VMware, torrent, and even games, other application lags even when quitted.

    For example, after using VMware Fusion, my RAM is used up to about 7GB.
    I check my Activity Monitor and iStat and still says so.
    So decided to free up RAM by using "iCleanmemory".
    After I free up to 5GB, my computer lags for a while.
    Such as Safari not opening, beach ball, jumping icon for couple min, safari opens but page not loading, etc.

    I never understood why my MBP would be doing this.
    After couple min of usage, it goes back to normal.
    But its frustrating that I have to wait a while until using the internet or anything else.

    Is there a solution? Or is this natural occurrence?

    I get the same effect with 8 gb, but I'm not promising others do too.

    You don't need that app. It can actually decrease performance. Launch Activity Monitor and click the System Memory tab at the bottom to check your page outs. Page outs are cumulative since your last restart, so the best way to check is to restart your computer and track page outs under your normal workload (the apps, browser pages and documents you normally would have open). If your page outs are significant (say 1GB or more) under normal use, you may benefit from more RAM. If your page outs are zero or very low during normal use, you probably won't see any performance improvement from adding RAM.
