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.

Olav van Schie:
Make your Laravel App Fly with PHP OPcache
Jun 14, 2017 @ 10:16:21

On his Medium site Olav van Schie shows you how to "make your Laravel app fly" with the help of OPcache. While OPcache isn't something that's specific to Laravel, he does include a package near the end that makes it easier to use it with the caching built into "artisan".

Every time you execute a PHP script, the script needs to be compiled to byte code. OPcache leverages a cache for this bytecode, so the next time the same script is requested, it doesn’t have to recompile it. This can save some precious execution time, and thus make your app faster (and maybe save some server costs).

He starts with a brief overview of OPcache and the main benefit it provides. He also shares some benchmarks he performed on a Digital Ocean server based on the results of performance testing the default Laravel "welcome" page. He then shows how to check and be sure it's installed and enabled on your PHP installation and some good default settings to configure in your php.ini. The post wraps up mentioning the package that helps integrate it with the Laravel application and the command required to clear out the OPcache on deploy.

Rob Allen:
Slim's route cache file
May 31, 2017 @ 09:35:15

In a new post to his site Rob Allen talks about how you can speed up the routing in your Slim framework based application using the route cache file.

When you have a lot of routes, that have parameters, consider using the router's cache file to speed up performance.

To do this, you set the routerCacheFile setting to a valid file name. The next time the app is run, then the file is created which contains an associative array with data that means that the router doesn't need to recompile the regular expressions that it uses.

He gives an example of how to enable the setting and makes the recommendation that it's only used in production. He includes a simple example that defines "25 groups, each with 4000 routes, each of which has a placeholder parameter with a constraint." The first run on a route responds in 2.7 seconds but, once the cache file is created, it drops down to just 263 milliseconds - a major improvement.

SitePoint PHP Blog:
Web App Performance Testing with Siege – Plan, Test, Learn
May 30, 2017 @ 12:27:36

The SitePoint PHP blog has a tutorial posted that wants to help you test you application and get the best performance from it. The tutorial introduces you to Siege, a performance testing tool that includes benchmarking functionality.

Almost anyone can build an app locally, deploy it to a server, and proudly show it to your friends. I hope you’ve already done all of this, and your project went viral, so you’re obviously here because you want to learn how to make sure your app is ready for some high traffic.

[...] In this article, designed to speed this [learning] process up, I will cover the basic concepts of testing the app (regression, load, and stress testing) with Siege</a and some tips and tricks I like to use when I’m testing my own web apps.

The tutorial starts with an overview of the types of testing and a few tips for making your testing successful and effective. Then, using a sample Symfony demo application, they show how to make basic requests using Siege and what kind of data the results report. With the basics out of the way, they then cover more advanced topics like concurrency and doing the actual performance testing. Based on the results, they see that caching content could definitely help and, after enabling that, see the numbers go down dramatically. The post ends with a look at other testing tools and some of the things you'd need to plan out when using Siege against your application to get the most meaningful results.

Danny van Kooten:
Moving from PHP (Laravel) to Go
Apr 27, 2017 @ 10:14:04

Danny van Kooten has an interesting post on his site sharing his experience in converting a Laravel-based application to Go, briefly describing some of the changes made, performance differences and the lines of code required.

Earlier this year, I made an arguably bad business decision. I decided to rewrite the Laravel application powering Boxzilla in Go.

No regrets though.

Just a few weeks later I was deploying the Go application. Building it was the most fun I had in months, I learned a ton and the end result is a huge improvement over the old application. Better performance, easier deployments and higher test coverage.

He talks about why he selected Go and some of the external services he would need to interface with to make the transition complete. He then gets into the actual porting of the codebase and some of the challenges involved to replace Laravel functionality. With the application ported, he then compares the performance of the Laravel application versus the Go version, sharing the request of requests/second for each. He finishes out the post looking at a lines of code comparison between the two and how testing was handled on the Go side.

Exakat Blog:
Moving from array to class
Apr 12, 2017 @ 11:18:42

In a new post to the Exakat blog there's a proposal to replace uses of arrays with classes to make scripts more efficient and handle resources better behind the scenes.

Ever since I started using PHP, arrays have always been my friend. They are versatile, they have a wide range of functions, and they are easy to use. I kept using them versions after versions, and even with PHP 7.2, I still rely on them a lot. Over the years, classes have also made their way into my toolset. They have a different usage : classes are for complex data structures, for business logic. Simple data structures get an array. Until we tried what seemed impossible : a moving from an array to a class.

He mentions some of the recent changes in PHP 7 that make the use of classes over arrays a bit more advantageous. He then gets into how to take advantage of these efficiency benefits in moving from arrays to classes. He uses an example from his own work in the Exacat engine, how he performed the replacement and a small caveat he found when working with functions requiring array input. He ends the post with some of the other benefits from making the move including performance enhancements, readability and reduced memory usage.

Battle Log: Symfony Routing performance considerations.
Feb 28, 2017 @ 10:55:24

In a new post to his site Frank de Jonge shares his "battle log" when looking into routing performance considerations in Symfony after a "deep dive" into the component's code.

Last week I took a deep dive into Symfony's Routing Component. A project I worked on suffered from a huge performance penalty caused by a routing mistake. This lead me on the path to discovering some interesting performance considerations. Some common practices align nicely with Symfony's optimisations, let's look into those.

He starts off by describing the process he took to start the investigation and what prompted him to investigate the performance issue. He talks about his use of profiling to locate the bottleneck and track down the root cause. He answers the five "why's" about the issue and uses that to guide an approach. Ultimately he located the source of the issue - YAML parsing that shouldn't have been needed - and what the component does to make it more performant in non-development environments. He ends the post with a list of four performance considerations as you're going through your own development to get the most out of the component.

Hooks, Line, and Sinker: WordPress’ New WP_Hook Class
Jan 25, 2017 @ 10:34:02

The Delicious Brains site has a new post looking at an addition to the WordPress platform allowing you to hook into the core - the WP_Hook class. In the latest release of WordPress this system received a major overhaul and in this article they share what's been updated and what kind of impact it should have on your code.

The hooks system is a central pillar of WordPress and with the 4.7 release a major overhaul of how it works was merged. The Trac ticket that initially raised an issue with the hooks system was logged over 6 years ago. After a few attempts, the updates finally made it into the 4.7 release and the venerable hooks system was overhauled. In this post I want to go over some of the technical changes and decisions that went into the new WP_Hook class. I’ll also go over some of the more interesting aspects of WordPress core development and look into what it takes to overhaul a major feature in WordPress core.

The post starts out with what's changed related to the hooks handling, mostly that the functionality has moved out into a new "WP_Hook" class. This migrates it way from being handled right next to the plugin logic. He details some of the behind the scenes changes to the code and changes made to help improve performance. The post finishes out looking at the backwards compatibility of these changes and what it means for developers upgrading to this new WordPress version (hint: not much).

Using Varnish on a Laravel Forge provisioned server
Jan 05, 2017 @ 14:19:15

Freek Van der Herten has a post to his site showing you how to set up Varnish with a Laravel Forge server. Forge is a service that makes it simpler to set up and manage servers and the applications installed without having to mess with the details yourself.

For a project we’re working on at Spatie we’re expecting high traffic. That’s why we spent some time researching how to improve the request speed of a Laravel application and the amount of requests a single server can handle. There are many strategies and services you can use to speed up a site. In our specific project one of the things we settled on is Varnish. In this post I’d like to share how to set up Varnish on a Forge provisioned server.

He gives a high level overview of what Varnish is and what benefit it provides to your application (complete with illustrations) and includes a link to a presentation introducing Varnish to PHP developers. Then he moves on to installing Varnish on the server, updating the VCL configuration file and opening a port for you to use when connecting to the Varnish service. He shows the difference in the response headers when Varnish handles the response and the updates you'll need to make to get your Laravel application to play nicely with Varnish with this package.

He ends the post with examples of how to test the performance difference and some final steps to update the config and have it run on port 80 instead of the default 6081.
