    We have an option to do it on a built in basis, but I couldn't figure it out. I also think that the ROM has to be set up for it to work properly. That and SDext.

    i would not advise to use it if u hv a slow sd card and might degrade ur sd card too.
    but it can improve multitasking

    I'll add to it by saying not to use this unless you know you have a fast RANDOM write SD card.

    The SD card speed ratings are for sequential writes (good for cameras) and even the fastest class 10 can have really really slow random writes. I've seen some famous brand name class 10 cards (even UHS1) benchmark at random writes speeds of 10KB/s.

    The only way to know if you have a fast random write card is to use a benchmark utility like CrystalDiskMark.

    confirmed. Was playing dragonvale, has some serious lag/freezes. Exited, ran this app. Said my SD card write speed was 3 mb/s while the recommended was 6 mb/s but I have experienced no lag in any app or in general while this has been activated.

    If I can figure out how to run a swap file it would be built in.

    I don't think it will be too hard.

    I'm going to try to shrink the ram disk first. I think some of the files that are in it aren't used very often and could be moved out. I need some time to test my idea.

    As far as the swap file, I think that's what the app does.
