Backend Time
Backend Time is the duration it takes for a website's Origin Server to process a request and generate the HTML for a page. For dynamic e-commerce sites, this often involves running database queries (e.g., to check stock levels), executing application logic, and building the final page. This processing time is a major performance bottleneck because it happens for every user on every page view. Speed Kit virtually eliminates Backend Time for the initial page load by serving a pre-built, cached version of the page instead.
