I did some performance benchmark with the P3 plugin, here are the results :
Site URL: http://www.mendoweb.be/blog
Plugin Load Time: 0.9152seconds avg.
Theme Load Time: 0.0666seconds avg.
Core Load Time: 0.1512seconds avg.
Plugin Impact: 78.8% (of page load time)
Total Plugins: 5 (currently active)
Crayon Syntax Highlighter: 55% 0.5035s
Jetpack by WordPress.com: 37% 0.3393
Wordpress Seo: 6% 0.0547
Other: 2% 0.0177
Also I know I have only a very few other plugins to compare Crayon with, but still, an average of half a second is enormous! (1) What makes Crayon take so much time ?
But the most interesting is that I don't even use it yet on the pages, so firstly it is loaded absolutely for nothing. Secondly, it shouldn't be formatting anything, (2) then how does that explain the runtime by Crayon ?
(3) Isn't there ANY way to load Crayon ONLY if there is actual code to format ?
