Easily compare performance between two WordPress core releases with benchmarking.

Based on this document and the handbook entry on benchmarking WordPress PHP performance, this repository provides a GitHub Action to automate this process.

Usage

Manually

Run the following command in the terminal:

./run.sh [old=latest] [new=trunk] [skip_init=false] [output=markdown] [skip_formatting=false] [print_to_files=false]

By default, it compares the latest stable release with the current trunk version. So ./run.sh is the same as ./run.sh latest trunk.

You can choose different versions of course. For example, to compare with the current RC:

./run.sh latest 6.3-branch

To skip the initialization steps when you want to run the benchmarks multiple times after another:

./run.sh latest trunk true

To test a specific WP version by ZIP file:

./run.sh latest https://wordpress.org/wordpress-6.3-RC2.zip

The default output is as Markdown tables. To get output data as CSV without formatted numbers:

./run.sh latest trunk false csv true

To pipe that output into (CSV) files:

./run.sh latest trunk false csv true true

This will result in four CSV files with the individual table results.

GitHub Actions

This repository provides a GitHub Action to compare benchmarks of two separate WordPress versions.

The results are posted as a job summary.

By default, it compares the latest stable release with the current trunk version. You can choose different versions of course.
