Hey Natalie, Sanford, My team is also in the process of measuring the performance of our website and have come to a similar conclusion regarding Munchkin's performance. Understandably, some of the functionality that leads to website slowdown is unavoidable for the script, such as the synchronous XHR requests that happen on link clicks. However simply switching off link-tracking isn't really a solution to this problem in my opinion. I think the best possible way of reducing the front-end performance impact of these scripts is to attempt do more of the work in the back-end rather than in the front-end. For example, I don't need to track navigation with JS - it can be tracked in the backend when a GET request is received for a page, as long as I can communicate with a Marketo API to pass on the necessary info. Does such an API exist, is there documentation for it? Currently, the synchronous link tracking slows down every navigation on our website by up to 70%, which is huge, so being able to perform this outside of the client's machine would be incredibly powerful.

A remedy, but if I understand that blog post correctly, there will still be a form popping into the document after load, which is still not ideal. I appreciate your advice on this matter hugely. ... View more

I definitely agree with you to a point, however Im forced to use the forms2 js so that our marketing team can edit the forms, so this puts me in a position where I am forced to use the js, but unable to have our bespoke (and most importantly, synchronously loaded) forms . I just think it's a shame that there isnt a simple API endpoint that can return the marketo form (and any relevant data) and have the forms js _not_ make a network request for it. ... View more

Thanks guys for your help and advice, that being said, I'm pretty disappointed with Marketo Forms as a whole from a dev point of view. I appreciate the features that the custom Marketo scripts offer, but I hate how heavily-imposed they are. Why am I forced to use this ill-fitting MktoForms script to do something as simple as retrieve a HTML form and then post data back with an Auth key? ... View more
