Preface

MySQL is still the world's most popular relational database, and yet, it's still the most unoptimized - many people leave it at default values, not bothering to investigate further. In this article, we'll look at some MySQL optimization tips we've covered previously, and combine them with novelties that came out since.

How to Optimize MySQL: Indexes, Slow Queries, Configuration

It’s not often that we, as PHP developers, need to worry about memory management. The PHP engine does a stellar job of cleaning up after us, and the web server model of short-lived execution contexts means even the sloppiest code has no long-lasting effects.

How to Read Big Files with PHP (Without Killing Your Server)

According to Builtwith.com , WordPress holds close to 50% of the CMS share of the world's top 1,000,000 websites. As for the ecommerce sphere, we're at 33% with WooCommerce. And if we cast a wider net, percentages go higher. Although we may complain that WordPress can get bloated, resource-heavy, and its data model leaves a lot to be desired, there is no denying that WordPress is everywhere.

WordPress Optimization

On top of the infrastructure of the internet — or the physical network layers — sits the Internet Protocol, as part of the TCP/IP, or transport layer. It's the fabric underlying all or most of our internet communications.

Apache vs Nginx Performance: Optimization Techniques

No one hates robust and scalable applications, especially when the database is growing quickly, and millions of requests need to be served on a daily basis. Profiling is a form of program analysis to measure the time and resources consumed by the program. With profiling, we can spot the performance bottlenecks in the code and do something about them. There is a variety of profiling tools out there, each taking a different approach.

Varnish Cache is an HTTP accelerator and reverse proxy developed by Danish consultant and FreeBSD core developer Poul-Henning Kamp , along with other developers at Norwegian Linpro AS . It was released in 2006.

How to Boost Your Server Performance with Varnish

When things go south with our applications — as they sometimes do, whether we like it or not — our log files are normally among the first places where we go when we start the troubleshooting process. The big “but” here is that despite the fact that log files contain a wealth of helpful information about events, they are usually extremely difficult to decipher.
