I finally figured out why my multitasking pane pulls up so slowly

After using iPhone for 2 years and another solid year of iPad, I've always wondered why my multitasking pane pulled up so much slower compared to my friend's iPhone, or the ones at Apple store. Turns out, it is because I have triple-clicking enabled.

So, if you have OCD like me, and wants are more "responsive" double-clicking experience, disable triple-clicking in settings. This can be simply done by unchecking all the options. Remember to disable "guided access" if you have iOS 6!

Try it out and you'll definitely see the difference!
