# Benchmark results

In this file, you will be able to see examples of benchmark results. These are provided as indicative results. Depending on your configuration, you might get way differents results

## Tests environnement

- Host OS: EndeavourOS x86_64
- Host kernel: Linux 6.19.10-arch1-1
- Host CPU: Ryzen 7 9800x3d @ 5.27 GHz
- Environnement: VM running in qemu-system-x86_64 version 10.2.2
- VM parameters: KVM enabled, 4096M of RAM, cpu set to host, running in single thread

The following tests are shown in the order the kernel run them. Please keep in mind that Pez isn't available until the Pez physical plane benchmark.
