Clear Linux with its PGO-optimized PHP package still delivers screaming performance for PHP compared to what is shipped by other Linux distributions.

PyBench benchmark with settings of Total For Average Test Times. Clear Linux: Xeon 8490H 2P was the fastest.
PyPerformance benchmark with settings of Benchmark: 2to3. Clear Linux: EPYC 9654 2P was the fastest.
PyPerformance benchmark with settings of Benchmark: crypto_pyaes. Clear Linux: Xeon 8490H 2P was the fastest.
PyPerformance benchmark with settings of Benchmark: django_template. Clear Linux: Xeon 8490H 2P was the fastest.
PyPerformance benchmark with settings of Benchmark: float. Clear Linux: Xeon 8490H 2P was the fastest.

Clear Linux was also delivering leading performance in the Python scripting benchmarks for these Linux server tests.

Ubuntu's default P-State powersave behavior on Sapphire Rapids was leading to much slower performance relative to AMD EPYC Genoa's "schedutil" governor default delivering effectively the same behavior as the performance governor in these Python benchmarks.

PyPerformance benchmark with settings of Benchmark: pickle_pure_python. Clear Linux: Xeon 8490H 2P was the fastest.
PyPerformance benchmark with settings of Benchmark: raytrace. Clear Linux: Xeon 8490H 2P was the fastest.
