The most successful engineering teams typically keep their workflow durations between five to ten minutes on average, according to CircleCI's 2022 State of Software Delivery. The median is 3.7 minutes.

Looking at our team's slowest GitHub Actions using our GitHub App, our longest workflow is just under 13 minutes. This excludes local builds and workflows.

But it's not unusual to see build times measured in hours, depending on the stack you're using.

LinkedIn's engineering org previously wrote about the steps they took to decrease build times from 60 minutes to 15 minutes for their largest microservice, improving productivity and team happiness.

What's the longest build or workflow time you've ever encountered? What tools were you using / could you fix it?
