Klaviyo affecting website performance - integrated with Shopify

Hi @afterS,

Welcome to the Community! The Help Center article you linked here is certainly a good place to start when it comes to troubleshooting any page speed issues you might be experiencing on your site. 

To note:
Klaviyo’s JavaScript onsite tracking is loaded asynchronously, which means that it should not impact your overall website performance. However, Google’s PageSpeed Insights and other site speed reports may still flag it as a contributing factor in your site’s load times.

You may also see an impact to page speed if you have more than one Form running on any particular page. Aside from it not being a best practice from a user experience perspective, having more than one sign-up forms or pop-up on a page could be what is causing the impacts you are reporting here. 

I’d recommend checking on your current form triggers and placements to make sure there is no overlap.
