It’s widely accepted that self-hosted fonts are the fastest option: same origin means reduced network negotiation, predictable URLs mean we can preload , self-hosted means we can set our own cache-control. Thus, on a 3G connection, it takes over nine seconds to download each file. On a high-latency connection, this spells bad news.

Examples of non-timing information you could send: HTTP Response status code, regions, request ids, etc. This is how they offer drop-in monitoring of all requests being made without us needing to change our code to monitor a request. For example, we almost always trigger image downloads by putting an img element in our HTML.

All of the SPECfp_rate2000 results were downloaded from www.spec.org, the results were sorted by processor type, and “peak floating-point operations per cycle” was manually added for each processor type. In these tests, we did not have the same ability to vary memory latency that I had with the 2007 Opteron systems.

The browser caches the results of these lookups, but they can be slow. This typically happens once per server and takes up valuable time — especially if the server is very distant from the browser and network latency is high. Get it wrong, and you’ve wasted time and resources in downloading something that isn’t going to be used.

After 20 years of neck-in-neck competition, often starting from common code lineages, there just isn't that much left to wring out of the system. For heavily latency-sensitive use-cases like WebXR, this is a critical component in delivering a good experience. Spurious reports of "10x worse" performance merit intense scepticism.

For this page to be done loading it needs to be responsive to user input — the “interactive” in “Time to Interactive” Browsers process user input by generating DOM events that application code listens to. Simulated packet loss and variable latency, however, can make benchmarking extremely difficult and slow.

However, unlike the early days of the web, static sites are no longer limited to developers working in a code editor. Piecing together a website using a WYSIWYG editor and seeing the code it generated was a fascinating and educational experience that sparked an initial interest in web design.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).

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”. For HTTP/1.1, Improving this situation was one of the main goals for HTTP/2.
