This bug exists since iOS 7.1 update and it was not fixed yet.
I have described the problem in the thread below.

Just to summarise if your carrier name is too long and does not fit on the status bar, it creates a delay in opening apps.
I have observed that the problem still exists in iOS 8 beta 3. I have reported the problem in apple like 4-5 times.
As i am not developer, can any developer here open a thread in apple to report this problem? It makes my iPhone 5s slower than 4s.
