Is Justuno Slowing down my website?

The simple answer is:  No, Justuno does not slow down your load speeds.

Justuno uses a asynchronous technique to load our widget. This means it does not block the loading of other content on your website and only loads AFTER your site has loaded. Therefore should not affect the speed.

Similar technology is utilized by Facebook, Google, Twitter etc. on their various javascript embed codes.

If you still suspect Justuno is slowing your page load, use the Developer Tools built into your web browser to measure the network timeline. Some online tools do not take into account the polling Justuno does after the page has finished loading, making the page load appear slower.

Code Size Specifications:

  • The embed code itself is 200 bytes, that's less then 1k.
  • The javascript file that is loaded asynchronously after your page has finished loading is relayed from Amazon's Cloudfront edge servers located all around the world enabling very fast & close deliveries.  It is a minified JS file that is gzipped and is only 10k.
