Please post an example where it is too slow. Make sure to test in release mode.

ex: when i want add 100 label to scrollview and i should check each label for emoji

Please post an example where it is too slow. Make sure to test in release mode. Post numbers. Post a real example.
One of the biggest programming mistakes is to assume that something is slow without testing it.

Watch the video tutorials for more information about this.

Based on the numbers I'm sure that you tested it in debug mode. Carefully read my previous answers.

The output when I run it in release mode:

time with check : 44
time without check : 19

Should we really talk so much about 25ms??????????????
