    What is System and compressed memory ?


    Why it's taking 380MB of my memory ? Does it important or there is a way to disable it ?

    @subi it must be an old Firefox. Every time I even open an empty tab with FF x64 45.0 my CPU meter jumps up near 100%. :) The 32 bit portable build does no better.

    Dear Chocolade,

    You are conflating 2 issues here. The purpose of memory compression is to reduce the amount of paging (i.e. writing to disk).

    How it works is described in @MilesAhead link above but basically the idea is that the OS will instead of writing information to disk when some RAM is needed use spare CPU cycle to compress it first.

    This is almost always a good thing unless you have a really old CPU or are running some CPU heavy task at the same time.

    What is doesn't do is make your I/O worse - it reduces it at the expense of CPU use.

    Post a picture of your Task Manager screen sorted by disk access but 6.1 MB/s should not be an issue.

    Please update your system specs as well.

    There are many issues with 100% disk use with practically no I/O but I don't really have a solution without more details..
