This strategy is quicker because the classmap can instantly return the full path to known files and avoids a filesystem stat operation. This strategy converts PSR-4/ PSR-0 rules into classmap rules. To improve performance, Composer offers three optimization levels these are: This slows things down quite a bit, but it is convenient in development environments because when you add a new class, it can immediately be discovered/used without having to rebuild the autoloader configuration.
Here’s a quote from the composer documentation which explains why:ĭue to the way PSR-4 and PSR-0 autoloading rules are set up, it Composer needs to check the filesystem before resolving a class name conclusively. While we’re all likely very familiar with using Composer to handle package management for us, if we don’t consider optimizing the configuration it generates, our applications aren’t going to perform as well as possible. And if you’d like to know more about how Xdebug works, check out the Xdebug documentation. To check if it’s installed, run php -m | grep -i xdebug or check your hosting provider’s administration panel. What’s more, it’s important to note that even though Xdebug was installed on the server - it wasn’t even enabled! While the performance benchmarks vary (they always do), one report on Stack Overflow showed a 50% performance boost by completely removing Xdebug. Sure, Xdebug is one of the most sophisticated and comprehensive profilers and debuggers for PHP, but it should never be enabled (even installed) on a production server, at least until Xdebug 3 is released and you should join us in supporting Derick to work on it. The next thing to check is that Xdebug is not installed on your production servers.
#Benchmark php 5.2 and 5.6 upgrade#
Make the upgrade and, as Rasmus said at phpCE 2018, go green(er) by reducing your hosting costs. So, if you haven’t already, it’s well past time you made the transition to PHP 7. What’s more, the final release of PHP 5, 5.6, went EOL (End of Life) 7 months ago, on Dec 31, 2018. If that’s not enough for you, check your benchmarks and see what they say.Īdditionally, PHP 7.0.0 was released on December 3rd, 2015, and the latest stable version, 7.3.6, was released on May 30, this year. Pantheon reported that PHP 7 gave a 64% improvement over version 5.3.Kinsta’s PHP performance benchmarks show WordPress 5.0 can execute 3x as many transactions as PHP 5.6 and.Official PHP benchmarks report that PHP 7 can execute twice as many requests per second when compared to PHP 5.6.However, based on reports by a range of different developers and notable hosting companies, the performance improvements are significant. Now, results will always vary, as no two applications are ever the same. It offers a significant speed improvement over any previous version. One of the best ways to improve PHP’s performance is to run the latest version (PHP 7).
By the time you’re finished reading, you should see at least a notable increase in the performance of your PHP application. In this post, I’m going to step through five of those ways. However, there are several things that we, as PHP developers and systems administrators, can do to increase its performance even further sometimes for almost no effort. Out of the proverbial, box, PHP provides decent performance. BONUS: We have discussed this topic with an expert in the PHP community in our podcast:
