Sheriffing Efficiency (November 2021)

Summary of alerts

Each month we’ll highlight the regressions and improvements found.

Note that whilst we usually allow one week to pass before generating the report, there are still alerts under investigation for the period covered in this article. This means that whilst we believe these metrics to be accurate at the time of writing, some of them may change over time.

We would love to hear your feedback on this article, the queries, the dashboard, or anything else related to performance sheriffing or performance testing. You can comment here, or find the team on Matrix in #perftest or #perfsheriffs.
