Greetings, Wordpress Wizard

According to kinsta.com research, Wordpress has become the most popular CMS system in the world. Big and small websites use it. People build complex webshops, galleries, booking systems, forums and corporate pages using it. Thousands of developers code for Wordpress every day and success of many projects rely on information and data stored and processed by it.

And every Wordpress installation run on a server, hosted somewhere around the globe. Server can be physical or virtual, it might run Unix, Linux, Windows or other OS, might have different processor, memory and storage hardware. Some are more powerful and some are less powerful, but most users never see these computers in real live.

The speed of your Wordpress depends on many factors. Number of plugins, logic complexity and data amount are those, which impact most of all. But what about raw server power? This project attempts to answer this question. Plugin, that we have developed will run unified tests and measure their execution times. Based on that we will score your server performance, so you can decide, if that is enough for your project or not.

Testing methodology

CPU and memory tests

• CPU speed is tested using checksum calculation function md5 together with random number generator and regex functions, that add good stress on processor.
• RAM speed is tested by creating huge in-memory array full of random data and performing trivial operations on its elements.

Filesystem tests

• Filesystem writeability test tries to write 50MB large file 20 times
• Small file IO test does similar write attempts, but instead writing 150Kb large files 500 times.
• File copy benchmark attempts to copy 50MB large locally hosted file 20 times.

Database performance tests

Consists of the following parts:

• inserting large amount of random data into temporary tables;
• running simple select and update queries without table joins;
• running more complex select queries using table joining operators.

Network speed test

Script tries to download large file from global CDN in order to make this test terrirory independant. On practice this is to-server network speed test - we believe it still can show tendency and quality of your internet connection.
