Lab: Profiling a misbehaving SBI handler

Lab Scenario: Slow AMF Handler

In this lab you will walk through profiling and optimizing a misbehaving AMF SBI handler that should complete in under 10 ms p95 but is observed at 80 ms p95 in production. The procedure is realistic — a handler that processes Namf_Communication_N1N2MessageTransfer requests, parses the incoming JSON, looks up the UE context, dispatches to internal logic, and returns a response. The lab demonstrates the standard profile-then-act workflow that 5GC performance engineers apply daily.
