PHP Performance: Additional CPU cores or Faster CPU cores

  Some time ago I received an email from a client experiencing slow performance issues with a LEMP (Linux, Nginx, MySQL and PHP web server). During a full audit, I found that the server’s load average was pretty low (see above screenshot). However, the website was indeed very slow. There were some misconfigurations, but one […]

PHP-FPM tuning: Using ‘pm static’ for max performance

Lets take a very quick look at how best to setup PHP-FPM for high throughput, low latency and a more stable use of CPU and memory. By default, most setups have PHP-FPM’s PM (process manager) string set to dynamic and there’s also the common advice to use ondemand if you suffer from available memory issues. However, lets compare the two management […]

Set PHP realpath_cache_size ‘correctly’

Back in 2012 I started enabling PHP realpath_cache_size and realpath_cache_ttl for the performance benefits. At the time, I followed settings I found here (has since been deleted). It bugged me that I was blindly setting the size of the cache without actually knowing how much storage was being used. In this post I will show you how to […]

Linux Performance: Why You Should Almost Always Add Swap Space

We know that using swap space instead of RAM (memory) can severely slow down the performance of Linux. So then, one might ask, since I have more than enough memory available, wouldn’t it better to remove swap space completely? The short answer is, No. There are performance benefits when swap is enabled, even when you have more […]

Linux benchmark scripts and tools

This list of Linux benchmark scripts and tools should prove useful for quick performance check of CPU, storage, memory and network on Linux servers and VPS. Recently, I used a Linux benchmark script which was no longer maintained by the. As a result, I compiled this quick list of scripts and tools for Linux benchmarking. […]

Quick Tips for a more stable Arch Linux experience

This short article aims to raise awareness on the best paths for a more stable Arch Linux experience. That’s not […]

What to buy for your Raspberry Pi

Updated March 27th 2019: Fixed broken manufacture product links and replaced with Amazon links. In another 5 years links will hopefully point to newer models, rather than to broken or discontinued product pages. Article originally posted March 2014.  Back in January 2014 I ordered my first Raspberry Pi (Model B revision 2). Very soon I realized […]
