"Spin up the environment" timing not included in total build time



Build times are reported as ~5 minutes, but when I click in on the details, each of the parallel branches of my build takes more like ~10 minutes. Upon closer inspection, there’s an extra ~5 minutes of “Spin up environment”, pulling the build image from docker hub.

This step used to be considerably faster (20s even when pulling full image), but I’m mostly concerned that it isn’t part of the build-time calculation. I track build time regression very carefully, and that’s much hard to do if I have to inspect every build.



Could you please send us a link to a build?

Feel free to contact support@circleci.com if you don’t wish to share the URL.



is a good example. all recent builds have this performance/reporting problem.


I went ahead and opened a bug ticket internally.
