Fundamentally, internet traffic can be broadly categorized into static and dynamic content. Yes, it’s a single file, but that’s not how it’s stored on the internet. This type of traffic originates directly from the server, making it more challenging to handle due to latency and server load considerations; it’s hard but not impossible.

Historically, NoSQL paid a lot of attention to tradeoffs between consistency, fault-tolerance and performance to serve geographically distributed systems, low-latency or highly available applications. However, consistency is a very expensive thing in distributed systems, so it can be traded not only to availability. Consistency.

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.

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”.

Modern browsers like Chrome and Samsung Internet support a long list of features that make web apps more powerful and keep users safer. The situation is even more acute in WebView IABs, which tend not to fully support features from these categories even when they appear available to developers via script. PWA Feature Detector.
