…heduling noise Evaluate the best of three 100k-order trials in perf_test and set the default throughput floor to 0.40 Mops/s (with OCAML_LOB_THROUGHPUT_FLOOR override support). This eliminates transient false failures caused by hypervisor CPU steal on burstable shared-core micro environments while preserving the regression guard against algorithmic regressions.
