I work on a publishing site and we use Twitter embeds in a lot of articles (below the fold). Recently we added preconnect to https://platform.twitter.com/widgets.js hoping to improve pagespeed. It didn’t seem to have a massive impact, but every little bit counts and I’ve learned this is a best practice.
We have cut down the connection and download time of this script, however this long execution bar did not go away. It looks like it’s extending the time of the document onload.
Is this problematic for pagespeed, and if so what can we do given that we cannot modify this script?
Thanks in advance.
