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. Ford, et al., “TCP

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. On Smashing Magazine, we use the postfix -opt for image names — for example, brotli-compression-opt.png ; whenever an image contains that postfix, everybody on the team knows that the image has already been optimized.

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.
