Have you disabled animations (aka 'prefer reduced motion') in the accessibility options of your device? I check for that and disable animations on the site. If not, then I'd be interested in the device you're using, to try and debug the animation. You're correct though, SVG animations can be resource-intensive. There's an interesting discussion elsewhere in the comments about how best to use the developer tools to debug poor performance in animations, but it can be a struggle.
