Detect performance regressions by measuring CPU instruction counts with the `profile` build mode and comparing against a stored baseline in speed_store. run_speed_tests / update_speed_test_results use perf counters for deterministic measurement across noisy hardware. Load when you need to catch a change that makes the simulator slower.
