There is lag when running on a smartphone.

hello. Nice to meet you.  
I created a WEB with ‘p5’.

1. When accessing through the smartphone’s ‘Internet’ or ‘Chrome’ URL
2. When entering ‘Webpage’ through ‘App’ on smartphone
3. When entering a PC URL

1 to 3. All work fine.  
However, when accessing from a smartphone, there is a ‘slight lag’.  
Is it because ‘p5’ is heavy? Otherwise, is there any solution?
