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

I vividly remember receiving a PC Magazine for my birthday with a trial of Dreamweaver. I had my website with funny photos and links to favorite websites live on the internet, and better yet, I could edit directly on the server. Smashing Magazine powered by Netlify. But, when it worked, it was magical. More after jump!

Barry Pollard, a web performance developer advocate for Chrome, wrote an excellent primer on the CrUX Report for Smashing Magazine. Chrome DevTools includes a separate “Performance” tab where the testing environment’s CPU and network connection can be artificially throttled to mirror a specific testing condition, such as slow internet speeds.

You’ve probably heard things like: “HTTP/3 is much faster than HTTP/2 when there is packet loss”, or “HTTP/3 connections have less latency and take less time to set up”, and probably “HTTP/3 can send data more quickly and can send more resources in parallel”. However, it is extremely challenging to actually deploy them at Internet scale.

This is because HTTP/3 and QUIC mainly help deal with the somewhat uncommon yet potentially high-impact problems that can arise on today’s Internet. Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Congestion Control.
