Performance issue when I try to animate multiple points

[Cmaxd]

I try to animate the position of multiple points (100,000 or more)，follow the official example, by updating a GeoJSON source.
The actual performance is bad (FPS is very low), so I want to know the bottleneck of animate multiple points or get some suggestions for optimization.

Here is my test code on JSFiddle:

Hi @Cmaxd -- unfortunately, I don't know of a current way to get fast performance animating that many points. We have a number of issues tracking performance improvements to setData -- #2275, #3692, #4271, #3812. Closing as a duplicate of those issues.
