This is really strange , lens has very fast focus speed , not far away from best newest Canon lenses , it can be slow in low light or when the subject is completely out of focus but this is the way those lenses work even new 500mm f4 II is slow when it loose focus completely.

Luckily when you know how to use the lens it almost never happens.

All the best

Zing!  Even if unintentional.
