The previous regression found in the 72-core machine is no longer present.\n\nBenchmark results with flag value \u003d HOST_CPUS showed:\n* 12 cores: -12.37% CPU, -8.88% wall\n* 16 cores: -5.82% CPU, +0.48% wall (~1s)\n* 72 cores: -2.98% CPU, +1.61% wall (~1s, statistically insignificant)\n\nPiperOrigin-RevId: 374620567\n",
