Three build-route tracks expose graph and fusion choices; full-engine timing and reference-output comparison precede feasibility filtering. No fabricated measurements, equality claims or cache-to-compiler steering remain.

Summary: NVIDIA introduces a global performance tuner for TensorRT that searches multiple build routes instead of accepting one local engine configuration. The workflow measures end-to-end inference time, tests candidate routes against an accuracy threshold and reuses cached measurements, giving engineering teams an explicit way to trade compilation effort against latency and numerical fidelity.

Why it matters: You will learn how to define an accuracy boundary, compare build routes with end-to-end timing and reuse measurements across tuning rounds. That procedure helps teams optimize inference without treating the fastest engine as acceptable when its output quality drifts.
