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

Plotted on the same horizontal axis of 1.6s, the waterfalls speak for themselves: 201ms of cumulative latency; 109ms of cumulative download. 4,362ms of cumulative latency; 240ms of cumulative download. When we talk about downloading files, we—generally speaking—have two things to consider: latency and bandwidth. It gets worse.

Server caches help lower the latency between a Frontend and Backend; since key-value databases are faster than traditional relational SQL databases, it will significantly increase an API’s response time.

During the Reinventing HPC panel session, there was some discussion of the cost of designing custom processors for HPC, and a statement that it was too high, in the hundreds of millions of dollars. The emergence of chiplet technology also allows higher performance and integration without having to design every chip from scratch.

Per the 2022 Web Almanac , which pulls data from real-world devices via the CrUX dataset , today's web offers poor performance for most users. From Edge's telemetry, we see that nearly half of devices fall into our "low-end" designation, which means that they have: HDD s (not SSD s). 2-4 CPU cores. 4GB RAM or less.

HTML, CSS, images, and fonts can all be parsed and run at near wire speeds on low-end hardware, but JavaScript is at least three times more expensive, byte-for-byte. Engineering is the discipline of designing solutions under specific constraints. You'll have to read on for what it is!
