Here are a whole lot of “Performance Tuning – Tips & Tricks” directly from the Nginx team. I’m sure you’ve seen bits and pieces of these all over the place, but it’s nice to have them all together and from the credible source as well.
Category: Web work
These days, most of my work is very related to the online world. Building web sites, reviewing web applications, integrating with web services, coordinating people who are far away from each other, etc. Whenever I find a new tool or service or an innovative, interesting idea about working online, I share it in this category.
The 2018 Guide to Building Secure PHP Software
“The 2018 Guide to Building Secure PHP Software” is an excellent guide to writing modern PHP applications with security in mind. It covers a bunch of the usual topics, but provides fresher solutions than most other similar guides.
Replaying JavaScript errors from the userland
I came across this interesting dive into monitoring, troubleshooting, and replaying JavaScript errors from the userland – “A user encounters a JavaScript error. You’ll never guess what happens next!!“.
This is not something immediately applicable for my projects at work, but gives me a lot to think about.
rector – reconstruct legacy PHP codebase to modern standards
rector looks like an excellent tool for those days when you need to rewrite large chunks of legacy code for the modern coding standards and best practices. Of course, there are IDEs that can help a lot with refactoring, but they are usually complex and slow. Regular expressions have always been a poor man’s choice for replacing old code with new code. But life can be easier and better. rector helps you find and replace things like namespaces, class names, method names and property names; change type hints and values of parameters; replace magic methods with their real implementations, and much more.
I’m sure I’ll be trying it out Real Soon Now ™, with the upcoming release of CakePHP 3.6.
PHP-FPM tuning: Using ‘pm static’ for Max Performance
“PHP-FPM tuning: Using ‘pm static’ for Max Performance” looks at different process management settings in PHP-FPM: static, dynamic, and ondemand, and the way they affect performance. The default – ondemand – might work well for you if you have a large server with plenty of resources and not so many actual visitors. Running on a smaller instance, or expecting high spikes of traffic might require you to look into your PHP-FPM configuration and adjust it. The article is just what the doctor ordered.
Personally, I prefer having a dedicated instance for the web server, but that instance being as small as possible. With that, figuring out the correct settings for static process management is easier. It also minimizes all those nasty cases of running out of memory, swapping, and having an excessive CPU utilization.  Which is especially useful when running on Amazon AWS instances.
