Casper Comment Section Slowing Down Mobile

When I run pagespeed I don’t get any issues with the loading of the comments section on desktop, but as for mobile the comments-ui.min.js takes nearly 2 full seconds on its own on load. Portal.min.js and sodo-search.min.js are also offenders on mobile but far less so.

Is there anything that can be done about that? Is that intended or unavoidable behaviour?
