WOW 🤩 The OpenJDK Vector API improvements to the JRuby JSON lib now improve encoding perf by better than 2X on real-world benchmarks, all without writing a line of assembly code! The potential of JRuby to accelerate Ruby apps grows with every JVM release.

@headius That context could, for example, be provided by a tracer (that's what we do at Datadog).
There is an ongoing discussion on how to best get "profiling labels" support for JFR. This would be an amazing tooling enabler, and support for it could then be added to JMC.
@headius The best way to do this is normally to have context labelling the events/samples, so that you can easier make sense of it. That context, could for example be provided by a tracer. For now you could emit contextual events.
