My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. It's an important vendor-neutral space to share the latest in technology.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. PRPL stands for Pushing critical resource, Rendering initial route, Pre-caching remaining routes and Lazy-loading remaining routes on demand.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Designed for the modern web, it responds to actual congestion, rather than packet loss like TCP does, it is significantly faster , with higher throughput and lower latency — and the algorithm works differently.

Fast-forward 30 years, and website technology has changed significantly — we have images, stylesheets, JavaScript, streaming video, AJAX, animation, WebSockets, WebGL, rounded corners in CSS — the list goes on.

Over those years, we have seen the technology stack evolve from server-rendered pages with some minor JavaScript and CSS to full-blown JavaScript applications. To mitigate the performance issues, we had to add a lot of (unbudgeted) extra servers and had to aggressively cache pages on a reverse proxy. Jonne Kats. Challenges.
