I use a lot of switching between apps, not some big apps (I guess), just browser, reader, dictionary, wikipedia. They have to rerun all the time. It takes like 5 seconds, not too much one might say, but it is, and its annoying.
I am using IPad Air (not 2). Guess 2 would be better. But what can i do now to make it fast and better memory management.
Throw me some technical stuff. System apps, cydia tweaks with jailbreak etc.
