Java Flight Recorder is basically 0 overhead as well and built directly into the VM.
- MrBuddyCasino 5y agoIsn't Flight Recorder profiling and not tracing? Or has this been added?
- NightMKoder 5y agoBoth JFR and agent based implementations only work with non async code. As soon as you do async anything, stack traces are no longer representative so automatic instrumentation is useless. That said, I’m really hoping Project Loom will fix that issue by getting rid of most async callback-style I/O.
