100% this, there is a nice presentation about the bloated web but I couldn't find it now. Remember that performance is a feature: https://blog.codinghorror.com/performance-is-a-feature/ https://blog.codinghorror.com/performance-is-a-feature/ That being said having a fast loading site and being able to serve a spike in load are two different issues (even if having fast loading pages in the first place obviously helps). Also don't forget that measuring (page size/response times/etc.) is the the first step. You can't optimize what you don't know!
