28-34 minutes. Massive highly-tested rails application, running on circleci. Only about 12 minutes of that is actually running tests, we parallelize them across roughly 60 containers, worked on by a team of ~100 engineers.
The truth is that most slow pipelines "could" be optimized to run wildly faster, but that it is costly to do so. You may be able to find low-hanging fruit that affect the build-time significantly, but most of the optimizations to be done are very large projects, like updating thousands of tests to be isolated from the database.
