Why this matters for the Core Web Vitals, and where to start fixing it
Page weight is a bandwidth problem. The network can only move so many bytes per second and every resource on the page competes for that capacity. The LCP image does not load alone. It shares bandwidth with every script, stylesheet and tracking pixel that loads at the same time. A heavier page means the main content arrives later.
Request count matters next to the bytes. Every request adds queueing and scheduling overhead. On a busy connection important requests wait behind unimportant ones. Script bytes keep costing after the download. The main thread has to parse and execute them, and that delays interactions (INP). The resource type breakdown shows where the bytes sit.
