MongoDB has the most advanced continuous performance testing I know about. MongoDB shared a lot of information on how we do performance testing and even open sourced some parts of it. Evergreen Continuous Integration: Why We Reinvented The Wheel , blog post from July 27, 2016, explains why and how it was done.

The result is a design for SQL Server 2016 that provides high availability for the most demanding workloads on the latest hardware with minimal impact and scalable for the future. However, if you are looking to accelerate your hardware, our Always On Availability Group design for SQL Server 2016 can keep pace. one without a replica).

Some of the built-in features ( wal_compression ) have been there since 2016, and almost all backup tools do the WAL compression before taking it to the backup repository. Such “torn pages” are corruptions from the database point of view. I couldn’t see any adverse effect on the TPS on quick tests.

Back in 2016, I gave a talk outlining the causes and effects of the terrible performance of web apps built using popular tools on the fastest-growing device segment: low-end to mid-range Android phones. In 2016, Jio swept over the subcontinent like a monsoon dropping a torrent of 4G infrastructure and free data rather than rain.

As an engineer on a browser team, I'm privy to the blow-by-blow of various performance projects, benchmark fire drills, and the ways performance marketing (deeply) impacts engineering priorities. With each team, benchmarks lost are understood as bugs. All modern browsers are fast, Chromium and Safari/WebKit included. Lower is better.

Improving latency and reducing variance allows teams to test other product hypotheses with less noise. Even junior PM s internalise the notion that product quality is at risk if tests are not built, automated, and tracked. These tests are expensive to run, so they must be chosen well.
