I chose to use a php script from and make some code adjustments because it doesnвЂ™t run on PHP 8.1. The benchmarks I did are very simple, but represent what we use most of the time.

MySQLi: New MYSQLI_REFRESH_REPLICA constant.

#Php 5.2 vs 5.6 performance series

These engine parts are available for the 'LA' series V8. We offer their entire line of muscle car restoration, stock rebuild, high performance and racing parts for the small block engines from Mopar Performance. Mopar Performance is the performance parts branch of Mopar.

Curl: File uploads from strings with CURLStringFile Small Block Mopar Performance Engine Parts 273 318 340 360 5.2 5.9 Magnum.

FPM: Configurable child-process spawn rate.

Hash functions accept algorithm-specific $options.

Array unpacking support for string-keyed arrays.

$_FILES: New full_path value for directory-uploads.

Phar: Added OpenSSL-256 and OpenSSL-512 signature algorithms.

Intl: New IntlDatePatternGenerator class Increase PHP application performance on Windows by caching PHP bytecode in.

#Php 5.2 vs 5.6 performance upgrade

All PHP 5.6 users are encouraged to upgrade to this version. Four security-related bugs were fixed in this release, including fixes for CVE-2014-3668, CVE-2014-3669 and CVE-2014-3670. Profiling was done with XDebug on all machines.I have run benchmark PHP 8.1 vs PHP 8.0 which was released on November 25, 2021. The PHP development team announces the immediate availability of PHP 5.6.2. Adding Opcache brings this down to ~400ms/req. But today they run blazingly fast (~1sec/request).

Update 2: Some some reason I can't remember we went back to activating PHP as an Apache Module on our servers (the same which deliver bad performance). With a file system, differences in write performance would probably smoothen out write differences due to the effect of the IO scheduler (elevator). This was for sequential read and writes on the raw raid types. Wp_slimstat::_get_browser (wp-slimstat.php:385) In July 2008, Jon Nelson made test of levels 5, 6, and 10, with differing chunk sizes from 64 kiB to 2 MiB on 4 SATA drives. Wp_slimstat::slimtrack (php::internal (507)) Php::call_user_func_array (wp-includes/plugin:507) Php::do_action_ref_array (class-wp.php:616)

Require wp-blog-header.php (index.php:17) Trace to _get_browser is: File (called from) This timeframe is to allow migrate the website to be compatible with 7.2. Restarting Apache/PHP fixed the problem for now. The hosting provider has given ten days time to upgrade from PHP 5.6 to PHP 7.2 Even they have asked to migrate PHP 7.0 and PHP 7.1 to PHP 7.2 If the upgrade is not done within the given time frame, the hosting provider will upgrade the PHP version to 7.2 themselves. Update: After some time, the systems seems to run out of memory, triggering out of memory exceptions and random allocations. No need to optimize the memory footprint of the script too. We want to get the script to run approximately the same speed on windows as on Linux (given the same setup regarding opcache/.).

We don't want to optimize this script (which we do know how to do). Profiling, system tests and configuration details are provided bellow. Evaluating 10.000 Regular expressions ( preg_match) takes about 90ms on Linux and 3000ms on Windows.

Double-check both Apache and PHP configuration for obvious configuration errorsДЄfter some profiling we quickly noticed that the evaluation of regular expressions is horribly slow on our windows machines.

Test different server & hardware setups.

Collect profiling data to identify the timekillers during script execution.

Make sure there is no antivir-software running or other windows domain stuff interfering.

So we took some steps to narrow down the problem: For static resources delivered by Apache only, speed is about the same as on linux. 400ms to 4000-5000ms for pages generated with PHP. If you roll back to PHP 5.6, you must update your website so that PHP 7 is supported before that time or your. However after having deployed this setup on a Windows Server 2008 RC2, we noticed a drastic performance difference compared to our other servers: page generation time goes up from avg. PHP 5.6 was replaced by PHP 7 in March 2019. WordPress is running exclusively on each server. For each installation, MySql is running on the same host. Our WordPress installation is managed by Git, all servers have the same source & WordPress setup deployed, only domains & actual data in the database varies. Our team is working is developing WordPress plugins and provides hosted instances on a couple of independent servers.
