 * Hey,
 * I use Cloudflare on our website, with Rocket Loader enabled to optimize site 
   load speed. Turning it on however, reduces the browser’s FPS to about 3-4.
    I
   did some research, and found that LC is the plugin causing this, specifically
   the function `dslc_check_viewport` in `/wp-includes/js/jquery/jquery.js`.
 * You can see it on this page: [https://releasecandidate.testbirds.hu/](https://releasecandidate.testbirds.hu/)
 * It’d be great if you could look into this, because I’d rather prefer to keep 
   the feature on for all scripts.

 * Hi,
 * dslc_check_viewport doesn’t do much. After you scroll down to the bottom of the
   page it stops doing anything at all.
 * Can you do a quick test? Switch to a different theme ( default WP theme would
   be perfect for the test ) and see if it’s still happening.
 * If it does let me know and we’ll figure out what to do next.
 * Regards,
    Slobodan

 * Hi,
 * I stripped the site from default content, so I couldn’t try with Twenty Sixteen,
   but Optimizer doesn’t seem to have the issue.
    Thanks for the response!

 * Hi,
 * Must have been some JavaScript in the previous theme that was hooking into the
   scroll event and causing a performance drop.
