PHP 7.1 vs 7.2 Benchmarks (with Docker and Symfony Flex)
Oct 17, 2017 @ 11:17:25

On the Symfony Finland site there's a new post sharing the results of some recent benchmarks of the differences between running the framework on PHP 7.1 and PHP 7.2:

PHP 7.2 will be launching soon, in fact, it has already reached Release Candidate status. I was exploring Symfony Flex with Docker setup and thought I would do a quick round of tests to compare the differences in PHP 7.1 and 7.2 (RC4) regarding performance with a few benchmarks.

[...] The benchmarked application is the Symfony Flex port of the hybrid application I did back in January. The project now has the required configuration to run it with Docker, and you can find the full source on GitHub.

The post then shares some of the results and conclusions of the test runs, showing the differences between the two versions. In one set of tests, they're calling the front page controller with Twig rendering and in the other a backend controller without the display rendering. PHP 7.2 ends up performing slightly better than PHP 7.1 overall but not by very much in most cases. The more dramatic change is on the backend, though, with a good jump in performance for a Symfony Flex application.

Symfony Finland:
Porting a Symfony 3 application to Flex
Jun 26, 2017 @ 11:42:12

On the Symfony Finland site they've posted a retrospective about moving an application from Symfony 3 to Flex including the work that was done in the switch and the performance of the result.

Earlier this year I did some experimenting with a Hybrid state object between Symfony Twig templates and front end JavaScript frameworks. Since that time I did that experiment, the Symfony Flex project has progressed. I thought I would try how to port the state prototype to Symfony Flex.

[...] In my case the application was rather simple and all built in the AppBundle, which is best-practise in Symfony3 for many applications. I mostly had to move files and configurations around and change namespaces.

He starts by spending some time talking about the difference between a Symfony 3 environment and the environment Flex provides. He then goes through the eight or so steps to move from one to the other including file/directory changes and configuration updates. Next comes the look at performance differences between the two. Unsurprisingly Flex came out on top in every measurement he threw at it.

In addition to the new structure, the apparent improvement in performance is obviously welcome. This would likely be even more evident where I could leave more dependencies out, for example in API workloads. This obviously won't magically push Symfony/PHP into Golang or Node.js territory for raw API throughput, but for existing large code bases it could provide a low-effort boost.

PHP 5.6 Vs PHP 7 – Performance Benchmarks With Laravel 5
Jun 16, 2017 @ 11:56:59

The CloudWays blog has posted an article sharing the results from some benchmarking they've done comparing Laravel 5 on PHP 5.6 versus PHP 7.

Laravel is rapidly becoming a popular choice for PHP projects. The framework has established its reputation after the release of version 5.x. In the same vein, PHP recently received a major update in the form of PHP 7.1.x.

It is an established fact that Laravel has a solid codebase and provides optimized performance for all lightweight and enterprise level applications. However no statistics about Laravel 5 benchmarks and its performance with PHP 5.6 and PHP 7 are widely available.

Using the Blitz testing tool and sample Laravel applications managed through CloudWays (on DigitalOcean), they benchmarked mean response times and the "hit rate" of the requested pages. Graphs are included of the results for both PHP 5.6 and PHP 7 and the post ends with a comparison of the results from the two scenarios with PHP 7 coming out on top.

Delicious Brains Blog:
Microcaching WordPress in Nginx to Improve Server Requests by 2,400%
Apr 26, 2017 @ 10:18:40

The Delicious Brains has a new tutorial posted sharing a method you can use to setup microcaching in Nginx for your WordPress installation and improve the performance of server requests by a large margin.

We’ve talked a lot about WordPress performance and hosting WordPress here at Delicious Brains. A common theme amongst those articles is the importance of page caching and how it’s arguably the best way to improve the performance of your WordPress site. [...] However, we’ve also alluded to the fact that page caching is difficult to implement on highly dynamic sites.

[...] In these circumstances page caching still has its place but the duration of the cache has to be significantly reduced. This is known as microcaching. Microcaching is a technique where content is cached for a very short period of time, usually in the range of 1-10 seconds. In this article, I’m going to demonstrate how to configure WordPress and bbPress with Nginx FastCGI caching.

They start off with some initial benchmarks performed using the Blitz.io service against a clean WordPress install on a Digital Ocean droplet. The first results are of a test with 100 concurrent users over 60 seconds (with not so great results). Then, using this method in the Nginx configuration, the site is retested resulting in much better performance but with one downfall - the pages are cached and no longer dynamic.

To resolve this they move to the "microcaching" solution, adding the caching to parts of the application that aren't the forum using the "X-Accel-Expires" header sent from WordPress. The post ends with a bit more tweaking to the configuration and some caveats to its use.

PhalconPHP: A Solution for High-load RESTful APIs
Apr 11, 2017 @ 10:26:37

The Toptal.com blog has a tutorial posted from Andrew Belousoff today sharing what he sees as a solution for high-load RESTful APIs in your application: PhalconPHP.

Suppose you need to create a high-load project based on a PHP MVC framework. You would probably use caching wherever possible. Maybe you would build the project in a single file, or maybe even write your own MVC framework with minimal functionality, or rewrite some parts of another framework. While, yes, this works, it’s a little bit tricky, isn’t it? Fortunately, there is one more solution that makes most of these manipulations unnecessary (save for the cache, perhaps), and this solution is called the PhalconPHP framework.

He starts off the article with a brief introduction to the PhalconPHP framework and some of the recent (2016) benchmarks of its performance against both raw PHP and other smaller, lighter MVC frameworks. With that out of the way he starts in on the creation of a sample project, first pointing out the difference between the "micro" and "full-stack" versions. He chooses the "micro" option for his API and walks you through installation of the framework extension, the directory structure it requires and what the code for the front controller looks like. From there he works up the rest of the code:

  • configuration handling
  • working with the DI container
  • creating the RESTful routes/controllers
  • building models
  • developing some business logic to work with user data

The post ends with a look at performing some testing on the result and mentions the addition of logging and caching functionality. He also points out one of the main disadvantages around using PhalconPHP - that it's an extension and is harder to customize than a PHP-land framework could be.

Hubert Brylkowski:
PHP can’t jump? Thing about recursion.
Dec 26, 2016 @ 15:14:37

Hubert Brylkowski has written up a post to his site looking at recursion in PHP and some of the limitations that can some with traditional methods.

Let’s get straight into the problem – assume we want to calculate nth Fibonacci number. Definition : F(n) = F(n-1) + F(n-2) with seed values F(1) = F(2) = 1 so the most intuitive way to do this is just from the definition (recursive). [...] Yay, everything works, so let’s play with bigger numbers. I would like to know the 35th Fibonacci number. On my machine it takes about 8 seconds. That sucks and takes definitely too long.

He talks about what some of the issues with this normal recursive method is (including how many times the function is called) and a possible way to resolve it. He updates this to use the BCMath handling as the numbers are starting to get larger but soon hits the max nesting level for PHP itself. Instead of traditional recursion, he suggests using a few functions/methods to to "jump" from one call to the next without one having to call the other. He includes some refactoring of this solution and a bit of benchmarking to show the performance gain over traditional methods.

Toon Verwerft:
Optimizing PHP performance by using fully-qualified function calls
Dec 22, 2016 @ 12:27:55

Toon Verwerft has a post on his site with details about a micro-optimization you can use in your PHP application by using fully-qualified function calls, specifying the namespace even for root level PHP functions.

Today, a little conversation on Twitter escalated rather quickly. Apparently PHP runs function calls differently depending on namespaced or non namespaced context. When calling functions in a namespaced context, additional actions are triggered in PHP which result in slower execution. In this article, I'll explain what happens and how you can speed up your application.

The conversation started with [this tweet]. To understand the difference between global and namespaced function calls better, I'll explain what is going on under the hood.

He starts with this "under the hood" functionality, showing an example of a user-defined, root level function and the opcodes that result. He compares this to the opcodes generated when a namespaced function is called and the extra checking that goes into it (including checking both the namespace and the root levels). Another tweet implied that, because of this difference in checking, fully-qualified function calls would result in a performance increase. He set out to prove it as fact and used the phpbench tool to run four tests with various namespaced and non-namespaced examples. He includes the code he used for the testing and the results from a sample execution. There is, in fact, a slight performance gain from the fully-qualified version. He finishes up the post with some suggestions on using this knowledge including the root-level namespacing for built-in PHP functions.

PHP 7.1 vs. 7.0 performance benchmarks with Symfony
Dec 12, 2016 @ 10:04:09

On the Symfony Finland site they've post together a post sharing some benchmark results of Symfony on PHP 7.0 versus 7.1, the most recent major release of the PHP language with some improvements of its own.

PHP 7.1 was launched on December 1st 2016. This was the first minor release after the release of 7.0 a year ago. PHP 7.0 was a revolutionary product, especially when it comes to memory usage and performance. PHP 7.1 is a more modest upgrade that brings new features and improved performance. But how much has performance improved from a year back?

The benchmarking uses the eZ Platform demo running a full CMS similar to the previous benchmarking done in 2015. The checks were run using:

  • a "clean" environment (no caching, PHP-FPM just restarted and no APC cache)
  • standard requests running in development mode
  • more requests but this time in production mode

The post shares the results with a few graphs showing them in terms of response time for both sequential and concurrent page requests.

SitePoint PHP Blog:
Benchmarking: Can AppServer Beat Symfony’s Performance?
May 19, 2016 @ 10:45:51

The SitePoint PHP blog has posted a new article comparing AppServer and Symfony on a performance level and wonders if the AppServer platform can outperform the framework on some base level functionality.

After the release of the first part of our Appserver series, it was clear through the ensuing discussions on both SitePoint and Reddit that we had touched a nerve for a good number of PHP channel’s devoted readers. I also quickly realized this new (for PHP) technology had a good number of serious doubters. One of the most poignant responses in the discussions was something along the lines of,

Needless to say, those doubtful and critical comments sounded like a real challenge. I was also very interested in finding out where appserver would land, if it were to be benchmarked against another well known PHP framework. [...] I decided to use my favorite framework, Symfony, to make the comparison. This is because appserver, as a stock PHP application server, also offers a good bit of important application functionality similar to Symfony.

They start with the approach they took to the comparison and how they set up the systems to evaluate the difference between the two (including hardware specs). The remainder of the post shares the results of several Apache Bench runs - the raw command line output - and more graphical versions of the same information (bar graphs). While there are a few "wins" on the AppServer side, overall it came in a bit slower (mostly because of the technologies involved in every request, however).

Mark Baker:
Anonymous Class Factory – The Results are in
May 13, 2016 @ 12:15:17

Following up on his previous post about anonymous classes and a factory to generate them, Mark Baker has posted about the results of some additional research he's done on the topic and four options he's come up with.

A week or so ago, I published an article entitled “In Search of an Anonymous Class Factory” about my efforts at writing a “factory” for PHP7’s new Anonymous Classes (extending a named concrete base class, and assigning Traits to it dynamically); and about how I subsequently discovered the expensive memory demands of my original factory code, and then rewrote it using a different and (hopefully) more memory-efficient approach.

Since then, I’ve run some tests for memory usage and timings to assess just how inefficient my first attempt at the factory code was, and whether the new version of the factory really was better than the original.

His four options that finally worked somewhat as he'd wanted were:

  • A factory that returns an instance of a concrete class using the traits he wants
  • A factory that returns an anonymous class extending a concrete class that uses the traits
  • His original Anonymous Class factory and extending the result with the traits
  • His second version of the Anonymous Class factory that creates the instance, caches it and returns a clone

He also includes the code he used to run the tests of each factory method and shares some of the resulting benchmarks (with a few surprises).
