Why does Vue take a long time to render after loading data?

Question

Vue.js

Good afternoon!
After the data arrives, vue changes the data in the application after a few seconds. 3-5 sec.
The data has already come from the server, but something is preventing them from being changed on the screen.
What could be the reason?

Answer 1

Open a console and look at network.
If it's really about rendering - hang timers on methods that process data.
