Hello,
the plugin scans the whole page and uses regular expressions to try and find jQuery-related code. It is mandatory, as lots of extensions actually add code to the body content of a page instead of its headers. Maybe you are having a rather long article (I am guessing) and the lookup takes longer than usual.
This makes me wonder if I should actually add an option to restrict the work of the plugin to the header area (for advanced users) to make it more efficient.

Hello,
can you check if the version 1.1.2 of the plugin improves the performance in your case?

Hello,
there is not much more I can optimize at this point in the plugin. Although you could try and comment one regular expression in the plugin's code (the one that gets rid of blank lines) that will not have any effect on the purpose of the plugin but may significantly improve the performance of your page. Let me know if that helps. If so, I will look into making this piece of code optional in the next version.
