Below are all the performances comparisons we have done so far (as of 2nd May 2024). We will regularly update and add new results.
These figures were generated using jmh (as documented on our blog ) with a standard set of images (also documented). They should be easy to replicate if you wish to validate, the code is on GitHub .
Your figures may vary depending on system but the overall results should be comparable.
