Marketo's embed code to load a form is like so:
<script>MktoForms2.loadForm("//app-sj03.marketo.com", "XXX-XXX-XXX", XXXX);</script>
The forms2.min.js file is a massive 164KB and since the script is not asynchronous, the rest of the web page will be blocked while the browser
downloads the 164KB file. This results in the user seeing a blank white page for a few seconds.
Is there an asynchronous script for loading forms or another more performant way to load a form?
