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. Best regards Alex
