PHP 7.0 RC1 Is Running Much Faster Than PHP5, But Still Not Beating HHVM
With PHP 7.0 RC1 having been released last week, I've spent a fair amount of time in the past few days trying out this first release candidate for the huge PHP 7 milestone.
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.
It took 330 seconds to run the entire test on the Phoronix Test Suite Git while the peak memory usage was at 612MB.
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.
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.
