Hi, What I can do to increase loading time prism.js file on the frontend? According to Google Speed Insight it takes 3 383 ms to load this file.

It's a tricky problem. I include the entire payload of PrismJS so support all languages, line numbers, and so on.

If you only want to support a few languages, you could go to the PrismJS website and build your own, only including those languages. Then create a yourapp/static/js/prism.min.js within one of your other apps that is included in INSTALLED_APPS before wagtailcodeblock.
