How to improve my extension source code don't generate so many timers?

[address@hidden]

I write an extension org-link-beautify (https://github.com/stardiviner/org-link-beautify). It use text-property to display all-the-icons icon for links.

When I use `list-timers`, I found many timers like this:

#+begin_example

I'm wandering is there someplace I write wrong in my source code:

https://github.com/stardiviner/org-link-beautify/blob/master/org-link-beautify.el

Or maybe this is an mechanism in Org Mode?
