alt Hacker News> Continuously capturing low-overhead performance profiles in production
It suprises me that anything designed by the OTel community could ever meet 'low-overhead' expectations.

Anything to actually add?
The reference implementation of the profiler [1] was originally built by the Optimyze team that Elastic then acquired (and donated to OTEL). That team is very good at what they do. For example, they invented the .eh_frame walking technique to get stack traces from binaries without frame pointers enabled.
Some of the OGs from that team later founded Zymtrace [2] and they're doing the same for profiling what happens inside GPUs now!
