Godot performance tests
This project contains a bunch of tests to measure Godot and GDScript performance for multiple engine versions at once.
There are two categories of tests:
Micro benchmarks: these are run in batches and measure how fast GDScript performs specific operations. They are purely time-based and their results are in microseconds. For example, how long it takes to assign a dictionary element.
Scale benchmarks: these are run individually. They measure speed and memory for a given metric over time. For example, how many bunnies can Godot render before getting under 15 fps.
You will also notice there are 3 projects which contain almost identical tests.
This is because major versions of Godot introduce big compatibility changes, and trying to keep the same project for all is a hassle.
However, some scripts can be copied more safely because Godot differences are centralized into a
polyfills.gd script, which wraps functions.
All those tests can be run automatically by running the
run.py script. This script contains some options at its top, which are described within the file.
The script will also run the tests for all Godot versions that you can provide. They are also listed in the script, but you may get them under a folder of yours before your start. You can also comment out versions you don't want to run.
Note that some tests may not be available for some Godot versions.
Results can be shown by running the
viewer. This is a Godot 3 application which will look into the results of previously-run tests and display a nice graph of the results over time.
Note that some results may not be viewable at the moment. Scale benchmarks need a visualizer.
