Page starts stalling after a few navigations

I’ve noticed recently that on my product page, after i click back and forth a few times between colors swatches and sizes, it starts stalling, and can take up to a couple of minutes to respond. It looks like the main page ends up in a stalled state for a while, but I can’t tell why. Any thoughts or ideas on how to troubleshoot?
