Featured PHP PHP 7.3 vs 7.2 vs 7.1 vs 7.0 (PHP-FPM) Benchmarks

eva2000 · Nov 25, 2018

Like I did for PHP 7.2 benchmarks, starting some PHP 7.3 comparison benchmarks as PHP 7.3.0 GA Stable is coming on December 3, 2018 and currently PHP 7.3.0RC6 is latest. For PHP 7.4 benchmarks, you can read them here.

PHP 7.3 vs 7.2 vs 7.1 vs 7.0 Benchmarks

Tests use following scripts

bench.php (official PHP file) - take the average of 3 runs

micro_bench.php (official PHP file) - take the average of 3 runs

detailed_benchmark.php - take the average of 3 runs

Notes:

PGO = Profile Guided Optimisations (for Wordpress, MediaWiki and Drupal like PHP web applications and similar PHP execution patterns.)

Centmin Mod defaults to non-PGO PHP-FPM builds for PHP 7 by default. PGO built PHP might be faster for some specific PHP code but slower for others so choose PGO wisely.

Latest tests are with Kernel updates for meltdown/spectre vulnerability patches which can reduce PHP performance compared to benchmarks done prior to November 25, 2018

Linux Kernel 3.10.0-862.14.4.el7 and 3.10.0-862.3.2.el7 were used

Times are in seconds where lower is faster

Centmin Mod PHP 7 Profile Guided Optimizations (PGO) Retuned

The above Profile Guided Optimizations (PGO) for PHP 7 versions seems to have somewhat regressed since last time I tested and for detailed_benchmark.php script the PGO runs are slower than non-PGO runs. So updated Centmin Mod 123.09beta01 PHP 7 PGO routines to fine tune them some more. I improved the micro_bench.php average run time under PHP 7.3.0RC6 PGO runs by ~6.5%.

PHP 7 PGO Custom Training

Centmin Mod 123.09beta01 also supports end user control to add additional variable = PHPPGO_INDEXPATH to specify additional PHP script paths which can be added to PGO training phase to optimise for those specific PHP code paths as well. So to add detailed_benchmark.php and it's tested PHP code/functions to PGO training phase and achieved ~25% faster detailed_benchmark.php run times on average !

Note that as part of PGO training during PHP compilation process, the detailed_benchmark.php script will be run 100x times to gather enough data to pass to PHP compile process for building a better optimised PHP binary. This adds to the PHP compile time. On my Intel Core i7 4790K each run of the script took ~2.9 seconds to run x 100 = ~290 extra seconds for PHP compile process. Small price to pay for ~25% faster performance for detailed_benchmark.php script and it's tested PHP code/functions which will translate the performance benefits to other PHP scripts which use similar PHP code/functions too. However, on slower VPS servers the detailed_benchmark.php script can take ~10 seconds per run x 100 = 1000 extra seconds or 16.67 minutes added to PHP compilation times ! Though it's usually compile once so for that extra up to 10-25% performance improvement might be worth it for some folks.

I set the variable PHPPGO_INDEXPATH to /FULL/PATH/TO/scripts/detailed_benchmark.php where the script is located on my server and then in persistent config file /etc/centminmod/custom_config.inc prior to centmin.sh menu option 5 PHP recompiles for PHP 7.3.0RC6.

Detected PHP 7.3 branch.
You can compile Zend OPcache (Zend Optimizer Plus+) support
as an alternative to using APC Cache or Xcache cache.
But Zend OPcache only provides PHP opcode cache and
DOESN'T do data caching, so if your web apps such as Wordpress,
Drupal or vBulletin require data caching to APC or Xcache,
it won't work with Zend OPcache.

End result is detailed_benchmark.php runtimes dropped from ~1.9923s to ~1.488s on average or ~25% faster when PHP 7.3.0RC6 was compiled with Profile Guided Optimization (PGO) training specifically for detailed_benchmark.php When combined with optimised PGO runtine improving micro_bench.php performance (1.9717 vs 1.8467), the combined effect is improving PHP 7.3.0RC6 PGO performance from total time of 4.3513 seconds down to 3.7287 seconds or ~14.31% faster now

Then I also recompiled PHP 7.2.12 with PGO tuned and detailed_benchmark.php PGO trained run to see how it would improve PHP 7.2.12 PGO performance. End result is detailed_benchmark.php runtimes dropped from 2.1243s to 1.6017s on average or ~24.6% faster when PHP 7.2.12 was compiled with Profile Guided Optimization (PGO) training specifically for detailed_benchmark.php. When combined with optimised PGO runtime was slightly slower micro_bench.php performance (2.0907 vs 2.0510), the combined effect is improving PHP 7.2.12 PGO performance from total time of 4.5916 seconds down to 4.0961 seconds or ~10.8% faster now ! That makes PHP 7.2.12 PGO tuned runs as fast as PHP 7.3.0RC6 non-PGO run times

Did the same for PHP 7.1.24 PGO tuned and detailed_benchmark.php PGO trained run and result was slower micro_bench.php performance (2.4050 vs 2.3393) and 23.6% faster for detailed_benchmark.php PGO trained run (1.7750 vs 2.3260). End result is total time improved for PHP 7.1.24 PGO run times from 5.083s down 4.5983 or ~9.5% faster. That makes PHP 7.1.24 PGO tuned runs as fast as PHP 7.2.12 non-PGO run times

Did the same for PHP 7.0.32 PGO tuned and detailed_benchmark.php PGO trained run and result was slower micro_bench.php performance (2.3350 vs 2.3343) and 23.8% faster for detailed_benchmark.php PGO trained run (1.8310 vs 2.4027). End result is total time improved for PHP 7.0.32 PGO run times from 5.1663s down 4.5957 or ~11% faster. That makes PHP 7.0.32 PGO tuned runs ~6% faster than PHP 7.1.24 non-PGO run times

PHP 7.3 Wordpress 5.0 RC1 Profile Guided Optimization Trained Benchmarks

Next I installed Wordpress 5.0 RC1 manually via WPCLI command line and not via Centmin Mod 123.09beta01 centmin.sh 22 Wordpress installer so that I can get a stock Wordpress 5.0 RC1 install and run PHP 7 benchmarks against it with both Profile Guided Optimizations (PGO) training specifically for Wordpress 5.0 RC1 index.php page and PGO tuned training for detailed_benchmarks.php script.

PHP 7 Wordpress 5.0 RC1 PGO Custom Training

Centmin Mod 123.09beta01 also supports end user control to add additional variable = PHPPGO_INDEXPATH to specify additional PHP script paths which can be added to PGO training phase to optimise for those specific PHP code paths as well.

I set the variable PHPPGO_INDEXPATH to /FULL/PATH/TO/scripts/detailed_benchmark.php where the script is located on my server and then in persistent config file /etc/centminmod/custom_config.inc prior to centmin.sh menu option 5 PHP recompiles for PHP 7.3.0RC6.

Notes:

As expected specific Wordpress PGO trained PHP 7 versions were the fastest within each major PHP 7.3, 7.2, 7.1, 7.0 branches for Centmin Mod 123.09beta01 built PHP-FPM versions.

Each version with WP PGO training allowed it to be almost as fast as the next faster major version. So Centmin Mod 123.09beta01 built PHP-FPM 7.0.32 and 7.1.24 with WP PGO training was nearly as fast as Remi SCL built PHP 7.2.13RC1 and Centmin Mod 123.09beta01 built PHP-FPM 7.2.12 with WP PGO training was nearly as fast as Remi SCL built PHP 7.3.0RC6

You can find the raw wrk-cmm benchmark numbers here.

PHP 7.3.0 GA Release Benchmarks

PHP 7.3.0 GA release is out now so retested my benchmarks outlined here with latest PHP 7.2.13, 7.1.24 and 7.0.33 final releases as comparison. For Centmin Mod 123.09beta01 PHP-FPM, I tested with and without PGO Wordpress trained profiles.

Tests use following scripts

bench.php (official PHP file) - take the average of 3 runs

micro_bench.php (official PHP file) - take the average of 3 runs

detailed_benchmark.php - take the average of 3 runs

Notes:

PGO = Profile Guided Optimisations (for Wordpress, MediaWiki and Drupal like PHP web applications and similar PHP execution patterns.)

Centmin Mod defaults to non-PGO PHP-FPM builds for PHP 7 by default. PGO built PHP might be faster for some specific PHP code but slower for others so choose PGO wisely.

Latest tests are with Kernel updates for meltdown/spectre vulnerability patches which can reduce PHP performance compared to benchmarks done prior to November 25, 2018

Linux Kernel 3.10.0-862.14.4.el7 used

Times are in seconds where lower is faster

Posted a request on twitter George Liu on Twitter as I want to revisit these PHP benchmarks for PHP 7.4 vs 7.3 vs 7.2 etc but on newer cpus like Intel Xeon E-2276 or AMD Ryzen 3600X + or higher. So if you have access to such dedicated servers or know of web hosts who can lend/sponsor for a few weeks ?

Click to expand...

FYI, I have already arranged access thanks to a kind web host so I am benchmarking and testing the following dedicated servers and will have full benchmark comparison review write up of these servers later on

Intel Xeon E-2276G Coffee Lake 6C/12T

Intel Xeon E-2288G Coffee Lake 8C/16T

AMD Ryzen 3600 Zen2 6C/12T

AMD Ryzen 3800X Zen2 8C/16T

AMD Ryzen 3900X Zen2 12C/24T

With possible access to Intel Core i9 9900KS 8C/16T and AMD Ryzen 3950X 16C/32T later on

All loaded with 1.2TB NVMe drives
