GPU fragment time

Why does the Webkit.GPU process occupy the fragment for so long? Is it related to shader complexity or read/write bandwidth? We found that these two performance data of safari's WebGL application are much higher than those of APP.
Phones run this kind of WebGL to render webpages and get hot after a few minutes.
