In this episode, Chet, Romain and Tor talk with Chris Craik and Rahul Ravikumar from the toolkit performance team. We talk about the recently released the macrobenchmark tool+library, in addition to other interesting bits like how the benchmark libraries work, how to use them, how they relate to system tracing, how to do performance debugging in general, and even a teaser of future performance instrumentation functionality that the team is working on. Chet, Chris, Rahul (top), Romain, and Tor (bottom), all looking unusually happy.   Related info: The Profile your app performance page for an overview of the performance tools and practices we offer.
