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.

Different browsers running on different platforms and hardware, respecting our user preferences and browsing modes (Safari Reader/ assistive technologies), being served to geo-locations with varying latency and intermittency increase the likeness of something not working as intended.

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. I vividly remember receiving a PC Magazine for my birthday with a trial of Dreamweaver. More after jump!

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. The seemingly obvious benefit of these technologies for users is guaranteed performance , so at times they might even prefer AMP-/Apple News/Instant Pages-links over "regular" and potentially bloated pages.

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.
