INSANE Speed enhancement by using a swap file! Credit for Chinese version goes here Credit for .plist version goes here The creator of the Chinese version has updated theirs with new features since I created this thread. Please update, if you prefer that version UPDATE: We have numbers! I can't read German, but ZhiZhi says that the NAND chip should last about 50 million write cycles, totaling to 7-10 years with constant read-write until it dies. Recently, developers have created a way to create a virtual swap file on your iDevice's disk drive, to store memory that would normally be in RAM, so your iDevice will have heaps of RAM left to deal with. There are two of these, referred to as the "Chinese" and "plist" versions. The Chinese version has one user-defined-static-sized file. The plist version creates and deletes 64mb files as needed. Here are some screenshots of my results: Chinese Please Register or Log in to view images plist (edited) Please Register or Log in to view images (Ignore battery, these were taken days apart) I've been told that this will decrease the life of the drive on your device. I'm assuming (correct me if I'm wrong) that using more memory at a time will decrease the life of the drive faster. Use with caution. On the Chinese version, I can run Touchgrind Safari Bloons Terminal Minigore App Store Mail Gangstar and iPod (With the idea of drive damage floating around, you should NEVER run this many apps at once. This is just a proof-of-concept.) with SBSettings reporting between 30 and 40 megs, more than what I could get after a reboot. SpringBoard is laggy like is has 8, however apps run like a charm once open. If it doesn't work, did you: Install it correctly? Chinese version, if the deb is installed correctly, should create a file called "com.apple.fm+vm.plist in the /System/Launchdaemons/ folder. The plist version's file should be put in the launchdaemon folder manually. Make sure the launchdaemons folder's permissions were 755? Change the file's owner to root and group to wheel? I'm currently investigating this. There's a thread with most information you need on another forum, but it's that one forum we're not allowed to talk about (sorry, just followin' the rules!). Like in the removing launchdaemons thread. Here's what I've found so far: Most other forum users agree it will wear it out, but in a matter of years. Not anytime soon. The Nokia N900 uses the same method to get increased speed. Most users also agree that the .plist version works better. (More information will be added as it is found) A user of that forum has also modified the .plist version to periodically clean like the Chinese one, and has also turned off encryption to make it work faster. It should look like this: It will not show up correctly in notepad. Edit it with iFile. SpringBoard will also crash the first time after using the edited file. Use Springback to back up your app locations if you need to.
