Our site's performance analyzed by Google PageSpeed Insights is pretty bad (scoring 12). The main issues are:
First Contentful Paint 3.1 s
Time to Interactive 12.5 s
Speed Index 7.7 s
Total Blocking Time 1,640 ms
Largest Contentful Paint 9.9 s
Cumulative Layout Shift 1.39
Most of the slow components seem to refer to the unused java-scripts from Squarespace. Should I use another template that has less unused code? Is there a smaller/faster template? I don't think the site design is really that complicated. We have a couple of pictures only.
