So the conclusion is:

There is no big performance difference between utf8 and utf8mb4

But if the collation not use default one, use like utf8mb4_unicode_520_ci, the sort performace will be 10-15% slower than use utf8mb4_general_ci

So this performance difference is not between utf8 and utf8mb4, it is between different collation
