This function tests how well your CPU and memory can handle and transform large text-data. These functions are quite important for parsing wordpress post-data, templates and filters. Keep in mind, that newer PHP versions handle this operation much faster.

Test CPU and memory with random binary data generation and memory prefill. While these are not critical Wordpress related functions, but they test CPU power and memory bandwidth.

Simple mathematical calculations using recursive function. Keep in mind, that newer PHP versions handle this operation much faster.

Simple mathematical calculations, but combined in iterative mode, instead of recursive. This test is less affected by selected PHP version.

Fast disk access time is very important for any software and Wordpress is not an exclusion. Higher score means faster disk access time and writing ability.

This score shows how fast your server is able to read and write local files. In general this replicates to the speed of disks, filesystem, system cache. Fast filesystem means faster code loading and execution.

This set of functions creates 3 database tables and imports large amount of data. High score means, how fast your database server is capable to write and aggregate data and indexes.

Functions, that show how good your database server can handle simple requests using indexes and query cache. Most requests to database are quite simple, but their count can be high, so it is important, that they execute really fast.

Complex SQL queries are those, which can create most of the load and slow down your Wordpress website. This is one of the most critical parameters. Our test queries fetch random data from several test tables. High score of this test depends on fast CPU, memory and disk of the database server.

Using extra plugins for making object cache persistent between requests minimizes load on database and often can significantly speed up your Wordpress website.

Testing write speed of persistent cache. You will see N/A result when your Wordpress does not persistent object cache.

Testing read speed of persistent cache. You will see N/A result when your Wordpress does not persistent object cache.

Testing mixed usage - reading, writing, update and deleting data from object cache, that simulates normal Wordpress workflow.

This is server download speed, which is speed to your server. While most of the traffic (for visitors) will always go out of your server, these tests can identify bottlenecks of server's internet connection speed.
