网站DOMContentLoaded快速但Favicon总是在21秒后加载？ 为什么？

Question

My website, https://homegift.vn, has a performance problem: DOMContentLoaded only 2s, but the favicon.ico always loads after 20s.

NOTE that:

• This was not happening before and I have not updated the code.

• Website Assets all optimized and can load fast.

• This happens for all pages (DOM maybe faster or slower, but all loads always finished after 21s with favicon).

I have tried to remove all slowing resources and third party content like Facebook.

Answer 1

Maybe this causion by some Script with DOM loaded event, i have try remove that and all look good now! Many thank @All
