The mean and percentile measurements hide this structure, but the rest of this post will show how the structure can be measured and analyzed so that you can figure out a useful model of your system, understand what is driving the long tail of latencies and come up with better SLAs and measures of capacity.

A message-oriented implementation requires an efficient messaging backbone that facilitates the exchange of data in a reliable and secure way with the lowest latency possible. Another element they have in common is that they are both consuming and producing messages. Apache Kafka is currently the leading project in this area.

Even with all of the available tools at my disposal, I still find myself reaching for several of them. In contrast, tools like DebugBear and WebPageTest use more realistic throttling that accurately reflects network round trips on a higher-latency connection. Lighthouse results. Real usage data would be better, of course.
