    From what I can gather on the Android operating system is that it's unnecessary to run a task killer because the OS will prioritize what applications need to be running to suit your needs/experience at that particular moment and kill all others.

    Furthermore the operating system will use the remaining phone memory as "swap memory" when RAM becomes scarce.

    If this is true, could moving all your apps to the sd card effectively double your available "RAM"???

    If not, would it be possible to implement this into a custom rom (bugless perhaps)???

    Essentially all your apps would run from your sd card and if possible the entire OS.

    I probably don't know what I'm talking about but I was curious.

    I've had a couple old win mobile phones before and when you open the task manager you see apps you didn't use be opened as well. I guess this comes with the ability to multi-task.

    I was like you before mad that there were a bunch of apps opened that I hadn't used. Then I uninstalled my task killer and noticed that there is no change in performance at all, as a matter of fact it made experience on the phone better because apps wouldn't have to reload all the time.

    I'm more concerned about the later part of this post though as far as being able to take advantage of the remaining available resources if you moved all your apps and even the OS (if possible) to the SD card completely.

    I just wish they would get the point that I don't want to use their damn Amazon MP3 application. Ever.

    Subscribing. I see this thread has kind-of been paused, but I'd like to know if there is indeed an increase in performance with Apps2SD...

    had this posted for awhile now with no responses to my original question...

    I think it can be done but I doubt anyone is seriously pursuing what I proposed.

    Yea...I noticed. With the problems I read some were having, I'm not sure there's a benefit to using this feature?

    Umm, the speed of the onboard RAM is WAY faster than the crappy SD card. No way would I want to run the OS off there.

    I haven't tried recently, but a while back I ran a rom with maybe half my apps or so on SD...

    Didn't notice any difference in performance. I don't think it gives you "extra ram" to utilize because I believe the internal memory is partitioned for system memory and apps storage. I may be totally off-base, but in System Monitor it would show like 160mb allocated to system memory, 90mb allocated to cache, and @ 250 or so allocated to apps. I realize it adds to like 512mb, don't really understand it.

    As far as I can tell, the only reason/advantage to moving apps to SD is if you are running out of internal storage space.

    Correct me if im wrong, but that issue with mounting the sd card to your pc is normal.

    If you apps are on your sd card, and you've mounted your sd card, your phone is going to have trouble accessing the sd card.

    Kind of like when you mount your sd card and try to use a file manager on your phone.

    ^ This. Probably depends a bit on the specific app as to how much of an impact there is on performance if the app and/or its data/cache/etc are moved to the SD card.

    Also, there isn't just one single variable (i.e. free memory) that affects performance. Consider the overall picture.

    I am by no means an authority on any of this so please correct me if I'm wrong here.

    Once you mount the SD card to the PC then the phone no longer has access to it until you dismount it from the PC and it is automatically remounted to the phone.

    Unless you are using an SD card with a high speed rating (class 6 or higher) then larger apps might be slower to load form the card rather than the internal memory, and from what I understand running the OS from an SD card would be a sluggish hell the likes of which I would only wish upon Steve Jobs.

    The benefit to installing apps to the SD card is to save space on the internal memory which becomes an important issue if you have a lot of apps. There might also be a benefit to having a separate partition on the card for apps that will allow you to restore apps and app data if you have to wipe the /system and /data partitions, but someone else will probably be able to give you better advice on that.

    This is very true, UNLESS you're using the Dual Mount SD Widget (in the Market). This widget (listed in the widget select list as "SD Share") is one of my favorite apps because, when you touch the widget, it mounts your SD for you and let's you access all the contents on your PC while also allowing you complete access to the SD card contents on your Droid. So your apps on SD don't become unusable while the SD card is mounted using the widget, and you can, for example, play MP3s from your SD card while exploring the contents on your PC.

    By the way, I have no affiliation whatsoever with this app or the dev, I just happen to love it.

    Sweet, that was the main issue that kept me from moving my apps. I will try out the dual mount app.

    I posted this in the LauncherPro Redraw thread here, but I'm under the suspicion the launcher API (meaning any launcher) enumerates the sdcard due to the Apps2Sd feature causing the launcher redraw people are experiencing. After moving everything back to the phone I've had no redraw issues, but it's only been around 5-6 hours but normally by now I would have had a redraw lag. I'll know more by the end of the day but I'd still suggest only moving apps to your sdcard ony if you are short on memory. As saif the internal memory is by far faster.
