This is a good test of your PC's drawing speed. If you see every frame displayed, it is running pretty well.
The SVG is 30,000 lines of code generating 1600 frames. The unzipped file is 23Mbytes.
There are a few places where frames in the original have been removed (after frame 60 for example) just to keep the size down.
If you are using Edge with the GSAP simulation of the SVG animation, rendering speed is very poor.
