xDebug is great development tool, but is slows down a web site significantly. During development cycle, it is desirable to turn on xDebug only when it is really needed. Let us show how to turn xDebug on, off, and set profiling modes in Laragon development environment. Also, we will show how to add buttons for these actions to phpStorm toolbar.

This is what final result will be (4 rightmost buttons).

First, let us create a command file to switch xDebug. We assume that we work on Windows 10 with Linux Bash Shell installed. In some folder, which is in Windows PATH, let us create two files: xdebug.bat and xdebug.sh.

Is it possible to “squeeze out” a high performance from a WordPress site? Our answer is yes! In this article we show how to set up a WordPress site configured to sustain high loads up to 10,000 clients per second, what equates to 800 million visits a day.

First, we need own virtual private server (VPS). For testing we used a VPS leased from DigitalOcean
(monthly rate USD 20) with the following parameters: 2GB of memory, 2 processors, 40GB on SSD. CentOS Linux release 7.3 has been chosen as the operating system.

The text below is almost a step-by-step instruction for experienced administrators. We will provide here only those parameters, which differs from default ones, and increase server performance. So, go ahead!
