I'm just pointing it out, in iOS 7 double pressing home opened multitasking immediately with a slower smoother animation. In iOS 8 beta 1 it has a delay just like pressing home to exit an app, but also a notably snappier animation, side by side iOS 7 opens multitasking first, once you're in multitasking it is faster in iOS 8. I doubt they are going to change it, it seems like an accessibility change for the triple press feature. This is not a beta glitch.
Either way please don't get defensive it was just an observation.
Not defensive, just pointing out that no benchmarking should be done with beta code regardless of the operating system. With that said, it's fun to talk about the changes and differences keeping in mind the results will change.
