> A profile of the unit tests in our system indicates that 2.62% of our tests by count are taking up 20.4% of our time. See [here|[https://docs.google.com/spreadsheets/d/1-tkH-hWBlEVInzMjLmJz4wABV6_mGs-2-NNM2XoVTcA/edit#gid=1501761592].]

> It's probably worth a little time to dig into some of those longer running tests and see how we can speed them up. This is an exercise we've engaged in repeatedly over the years with good results; we should also consider automating this test profiling process as well as extend it beyond just unit testing into in-jvm dtests and python dtests as well.
