    I have a late 2013 iMac running Mavs with 8gb RAM.

    I noticed that whenever my machine comes out of sleep, it has swap files of around 20 MB and 500 MB Compressed, even though Memory Used is only 2-3 GB. Memory pressure is slightly higher than usual but still green.

    When the machine is awake, piling on the pressure doesn't lead to swap file creation, only Compressed Memory which I guess is normal under a heavy load.

    So I believe that sleep is causing this. Is this normal ?

    Thanks in advance !!!

    I have a 1TB Fusion Drive btw.

    Pretty sure this is normal. When sleeping, most operating systems (most likely OS X Mavericks included) will write a page file to disk as an aid to assist it when coming out of sleep. I wouldn't be concerned about it.
