Ln 811 Performance Profiler
This profiler captures the full picture: CPU, memory, I/O, and wall time across your call chain, even following HTTP calls into other services if the code is accessible. It autodiscovers or generates benchmark tests when you don't have them, runs a baseline, traces through your functions to build a suspicion stack, then instruments the hot paths with stack-specific profilers. The workflow is structured around the "5 whys" principle, so you get root causes like misconfigured connection pools instead of vague "this function is slow" reports. Use it when you know something is slow but need the data to prove where and why before you start optimizing.
