Of course, most of my PHP interest revolves making sure it's running well for the Phoronix Test Suite, Phoromatic, and OpenBenchmarking.org. My latest results do show PHP 7 being much faster than the current PHP 5.6 stable series, but not quite as fast as Facebook's latest HHVM packages.
The benchmarks today are from an Intel Haswell-E Xeon system running Ubuntu 15.04 x86_64. First up are the PHP 5.6 results as packaged in Ubuntu Vivid. All of the tests were running the Phoronix-Test-Suite code on GitHub as of today while running phoronix-test-suite debug-self-test, which stresses a lot of the internal hot code-paths of PTS. There's a lot of XML parsing, JSON handling, computations, DOM interactions, graph rendering, etc.
PHP: 5.6.4-4ubuntu6.2 DETAILED_SYSTEM_INFO: 0.187 seconds LIST_AVAILABLE_TESTS: 0.006 seconds LIST_AVAILABLE_SUITES: 0.467 seconds INFO: 0.602 seconds CLONE_OPENBENCHMARKING_RESULT: 13.224 seconds RESULT_FILE_TO_TEXT: 0.221 seconds DIAGNOSTICS: 0.007 seconds DUMP_POSSIBLE_OPTIONS: 0.001 seconds DEBUG_RENDER_TEST: 95.429 seconds ELAPSED TIME: 330.432 seconds PEAK MEMORY USAGE: 612.5 MB PEAK MEMORY USAGE (emalloc): 568.698 MB
It took 330 seconds to run the entire test on the Phoronix Test Suite Git while the peak memory usage was at 612MB.
PHP: 7.0.0RC1 DETAILED_SYSTEM_INFO: 0.166 seconds LIST_AVAILABLE_TESTS: 0.003 seconds LIST_AVAILABLE_SUITES: 0.369 seconds INFO: 0.432 seconds CLONE_OPENBENCHMARKING_RESULT: 12.491 seconds RESULT_FILE_TO_TEXT: 0.201 seconds DIAGNOSTICS: 0.006 seconds DUMP_POSSIBLE_OPTIONS: 0.003 seconds DEBUG_RENDER_TEST: 42.920 seconds ELAPSED TIME: 169.775 seconds PEAK MEMORY USAGE: 455.73 MB PEAK MEMORY USAGE (emalloc): 361.571 MB
The PHP 7.0 RC1 result is certainly impressive! The performance was nearly doubled, which is what is largely expected with PHP 7 being about twice as fast as PHP 5.6. The peak memory usage was also lower at 455MB. The big improvement to DEBUG_RENDER_TEST is also beneficial to Phoronix readers using OpenBenchmarking and LinuxBenchmarking.com as once deployed there the large result files should load much faster.
PHP: 5.6.99-hhvm DETAILED_SYSTEM_INFO: 0.510 seconds LIST_AVAILABLE_TESTS: 0.019 seconds LIST_AVAILABLE_SUITES: 0.493 seconds INFO: 0.655 seconds CLONE_OPENBENCHMARKING_RESULT: 11.527 seconds RESULT_FILE_TO_TEXT: 0.229 seconds DIAGNOSTICS: 0.038 seconds DUMP_POSSIBLE_OPTIONS: 0.006 seconds DEBUG_RENDER_TEST: 27.096 seconds ELAPSED TIME: 121.72 seconds PEAK MEMORY USAGE: 8755.141 MB PEAK MEMORY USAGE (emalloc): 510 MB
When using the official HHVM packages for Ubuntu 15.04, the performance did outpace the current PHP 7.0 development version. HHVM 3.6.99 ran the same test in 121 seconds compared to the 169 seconds with PHP 7.0-RC1. However, the reported peak memory usage was significantly worse... 8755MB on HHVM vs. 455MB with PHP 7. I even had to adjust the memory_limit within the PTS code to accommodate HHVM running the test without a fatal error.
Stay tuned for more PHP 7 benchmarks shortly on Phoronix.
