Welcome to the Shopify Community!
This is Syed Mustafa a professional Shopify Developer. As I'm sure you well know, page speed has become a factor for ranking in the search engines. That's why if you're investing lots of time and money into getting the rankings you deserve, you shouldn't be blowing it by having a slow website.
Longer load times have also been shown to negatively affect conversions.
