Think about your pipeline. You have integrations dedicated to unit and visual regression tests. You have others set aside for code quality, coverage, and deployments. A suite of automation entirely dedicated to making sure that nothing breaks, and that reviews can take place on a qualitative level once all the boxes have been checked. But what about performance? How confident are you that a new feature doesn’t result in a regression? Are you able to determine who exactly experiences degraded performance and when? How do you pinpoint the problem causing the issue, and know how to resolve it quickly? One tool that provides exactly these insights - from individual commits in development through to production monitoring - is Blackfire.io. Blackfire is unique, because it contains not only an application performance monitoring solution for your production site, but also a profiler that makes it possible to define per-commit builds across multiple user scenarios that tie performance metrics into your existing pipeline. That means nothing can reach production that sacrifices user experience, and that you can make performance improvement tuning into a regular, incremental part of your lifecycle. In this talk, you’ll get an introduction to Blackfire, and how it can be integrated into your workflow for more performant Drupal applications.
