PHP PHP 5.7 almost 2x times faster than PHP 5.6

eva2000 · Jul 22, 2014

Great news for PHP users regarding PHPNG (PHP 5.7) PHP NG now nearly TWICE as fast as PHP 5.6 | _ck_ says... and PHP NG within 10-25% of HHVM performance | _ck_ says...

PHP 5.7 (aka PHPNG) is still in alpha development, however it is starting to show breathtaking performance improvements over 5.6 while maintaining virtually complete compatibility.

Dmitry Stogov has been hard at work since his first announcement in mid-January 2014 to keep folding in more and more ideas to increase PHP speed (with contributions by Xinchen Hui and others).

Six months later in mid-July, his efforts are really bearing fruit and PHP 5.7 is about to become nearly 100% faster than PHP 5.6 when rendering the front page of a stock WordPress 3.6 installation:

PHP 5.6, 1000 renderings of WP front page = 26.756 seconds
PHP 5.7, 1000 renderings of WP front page = 14.810 seconds

PHP NG within 10-25% of HHVM performance
Zeev Suraski (CTO of Zend and therefore an extremely qualified authority on PHP NG) has written a fascinating article comparing the performance of PHPNG against the current HHVM versions. A must read.

Amazing speed up there with PHP 5.7 (phpng) compared to PHP 5.6 !

Centmin Mod is readying support for PHP 5.6 RC releases and you can test it via instructions at PHP-FPM - PHP 5.6 support testing for .07 betas | Centmin Mod Community.

Might see if PHP 5.7 (phpng) can also be tested too

Update: Centmin Mod now supports auto installation of PHP 7.0 / PHP NG via it's menu based install method.

Ah you beat me to it.. for PHP 5.7 should be same install method work around as for PHP 5.6 https://community.centminmod.com/threads/php-5-6-support-testing-for-07-betas.559/ - manual download to /svr-setup in naming format of php-5.7.0.tar.gz then running menu option 5 to upgrade PHP and specify PHP version = 5.7.0

or did you bypass the Centmin Mod menu option 5 method ?

edit: I guess you bypassed the menu option 5 as there's quite a few file edits to make it work with PHP 5.7.0 https://community.centminmod.com/th...-testing-for-centmin-mod-betas.892/#post-3957

Very small world that I actually ran into the author of the blog at http://ckon.wordpress.com/2014/07/14/php-5-7-twice-as-fast/ on centos.org forums for an unrelated topic (MariaDB systemd/init.d CentOS 7) https://www.centos.org/forums/viewtopic.php?f=47&t=47373

hungphutho · Jul 23, 2014

No , I edited centmin.sh

PHPMVER=$(echo "$PHP_VERSION" | cut -d . -f1,2)
if [[ "$APCINSTALL" = [nN] || "$ZOPCACHEDFT" = [yY] && "$PHPMVER" != '5.7' ]]; then
zopcacheinstall
fi

# if PHP_VERSION = 5.5 will need to setup a zendopcache.ini settings file
if [[ "$APCINSTALL" = [nN] || "$ZOPCACHEDFT" = [yY] && "$PHPMVER" = '5.7' ]]; then
zopcache_initialini
fi

php_configure.inc

if [[ "$PHPMUVER" = '5.6' || "$PHPMUVER" = '5.7' && "zendopcacheon" = [yY] || "ZOPCACHEDFT" = [yY] ]]; then
Download source to /svr-setup
I then select menu 5 ,

Nice, guess it works on CentOS 6.5.. not as lucky with CentOS 7.0 + PHP 5.7 https://community.centminmod.com/threads/php-5-7-phpng-support-testing-for-centmin-mod-betas.892/ hehe. Ah forgot about php_configure.inc

hungphutho · Jul 23, 2014

Yes , Centos 6.5

ok seems PHP NG should be PHP 6.x not 5.7 according one of the PHP devs at http://www.reddit.com/r/programming/comments/2ardou/php_57_aka_phpng_is_now_nearly_twice_as_fast_as/ = nikic http://www.reddit.com/user/nikic

nikic is a PHP core developer - he likely knows what he's talking about.

phpng is still under heavy development, and I believe from what I've read it breaks compatibility with extensions (which would be a good reason for it being a new major version). Which is why other concurrent proposals haven't been merged in yet (they're basically waiting for phpng to stabilise before attempting to merge other proposals).

5.7 is likely just a placeholder value since they didn't know when they started the branch where it would end up.

This is what happens when you parrot figures on a developer wiki without knowing what you're talking about.

And it's not even really suitable for /r/php, nevermind /r/programming as, from what I read on php-internals, this is still alpha quality stuff that only those who know what they're doing should be touching.

I am certain that it will not go into PHP 5.7 - it changes too many internal APIs for that (i.e. thiry-party extensions need to be significantly modified to work with it.)

That it will be the basis for PHP 6 (or whatever the name of the next major version is) is not yet officially decided, but I consider it very likely.

A number of other patches/proposals targeting PHP 6 (as of now those are uniform variable syntax, native big integers and abstract syntax tree) are branched off phpng.

Those gains on WordPress are pretty incredible.

eva2000 · Jul 24, 2014

Indeed it is. Added auto download support to Centmin Mod .08 betas for PHP 5.7.0 / PHP NG at PHP-FPM - PHP 5.7 (PHPNG) support testing for Centmin Mod betas | Centmin Mod Community. So much easier to test PHP NG if you want

In the graphic, it appears that the HHVM module can still be a good choice vs. PHP 5.7, alpha version anyway.

Any particular reason why Wordpress and Drupal don't perform quite as well with PHP 5.7 as some of the other tests?

Probably how each respective PHP app is coded ? The full details of those benchmarks by Zend CTO are at http://zsuraski.blogspot.com.au/2014/07/benchmarking-phpng.html but it doesn't go into such details though. Would be interesting to see Zend Opcache memory used size for each of those tests and PHP apps.

SneakyDave · Jul 24, 2014

Yeah, just curious if Wordpress and Drupal are using newer PHP code functions or certain PHP functions that might not show up as much in the other deployments. I'll do some investigation, thanks for the info.

yeah I wouldn't know myself. I'll stick with some synthetic tests first heh https://community.centminmod.com/th...ng-for-centmin-mod-betas.892/page-2#post-4033

eva2000 · Jul 27, 2014

looks like PHP NG might be PHP 7 according to ck's comment at http://ckon.wordpress.com/2014/07/17/phpng-hhvm-performance/

Note that phpng is about to be moved into the master branch (trunk) for PHP as PHP 7 if the votes go smoothly this month. Will probably happen by end of August.

So you’ll be able to add an option to just build the php trunk. The problem is they may break some backwards compatibility by the time they are done messing around with the rest of it. There is talk of removing mysql_* functions which would be a setback for compatibility.

Given that PHP 7 performance has pretty much caught up to HHVM, I've setup my first live site using Wordpress at wordpress7.centminmod.com on 2GB DigitalOcean VPS Droplet Server for testing CentOS 7.0 + Centmin Mod .08 beta LEMP web stack and PHP 7.0.0-dev (PHP NG)

That means you can't use any of the caching extensions? How does that affect the performance of the site?

Well Wordpress doesn't need to use any of those cache mechanisms like Memcached, as the auto installer uses WP Super Cache plugin which is static file caching and works well from Blitz.io benchmarks ~4,000 user stress test = 151.9 million hits/day Wordpress Nginx Auto Installer Script
