This time we're going to hack on Vernier, a profiler for Ruby. I'll have John Hawthorn (author of Vernier) on as a guest. We're going to try adding allocation profiling to Vernier, and if we have enough time we'll try doing some allocation profiling on Mastodon.
I've done a live stream about profiling in the past, and you can find it here:
