Ruby 2.1: Profiling Ruby Â· computer talk by @tmm1
24 Dec 2013 Ruby 2.1 is shipping with rb_profile_frames(), a new C-api for fetching ruby backtraces. The api performs no allocations and adds minimal cpu overhead making it ideal for profiling, even in production environments. I've implemented a sampling callstack profiler for 2.1 called stackprof with this API, using techniques popularized by gperftools and @brendangregg. It works remarkably well
