As developers, we rightfully obsess about the customer experience, relentlessly working to squeeze every millisecond out of the critical rendering path, optimize input latency, and eliminate jank. And, of course, the result needs to be seamless and delightful — dare we say, even fun — to develop and maintain. Ilya Grigorik.

Options 1 and 2 are of course the ‘scale out’ options, whereas option 3 is ‘scale up’. When used in prevention mode (IPS), this all has to happen inline over incoming traffic to block any traffic with suspicious signatures. This makes the whole system latency sensitive.

As defined by the Google SRE initiative, the four golden signals of monitoring include the following metrics: Latency. Latency is the amount of time, or delay, a service takes to respond to a request. Traffic refers to the amount of user demand, or load, is on the system. Monitoring can provide a way to differentiate between.

There are ways around that, of course. In contrast, tools like DebugBear and WebPageTest use more realistic throttling that accurately reflects network round trips on a higher-latency connection. Real usage data would be better, of course. That’s the “thing” I’ve been missing in my performance efforts.

This is a complex topic, but to borrow from a recent post , web performance expands access to information and services by reducing latency and variance across interactions in a session, with a particular focus on the tail of the distribution (P75+). Consistent performance matters just as much as low average latency. What's the problem?

Not as much as we'd like, of course, but the worldwide baseline has changed enormously. There are differences, of course, but not where it counts. Sadly, data on latency is harder to get, even from Google's perch, so progress there is somewhat more difficult to judge. Talk about a hard target. I'm happy to report that it has.

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).

Finally, not inlining resources has an added latency cost because the file needs to be requested. All of this is, of course, still true for HTTP/3 as well.
