# Top runs: * **Highest FPS**: `BORE` with an average FPS that is significantly higher than the other configurations. * **Smoothest FPS**: `flash-k` has the smoothest performance with the lowest FPS variance and standard deviation. * **Best overall**: `BORE` offers the best overall performance due to its combination of highest frames per second and a reasonable FPS stability compared to its mean FPS. # Issues: * The `bpfland-no-preempt` configuration has a notably lower average FPS compared to others, with approximately 15-20% lower performance than the rest, indicating a significant performance issue regardless of the similarity in hardware and software configuration. * The CPU load for `lavd` is slightly more variable with a higher variance compared to others, showing higher fluctuations despite using the same configuration. * The `lavd` configuration uses more swap space on average, approximately 2% higher than an optimal pre-allocated value, potentially affecting system efficiency slightly. # Summary This benchmark compares the performance of various kernel schedulers on `CachyOS` with identical hardware: an `AMD Ryzen 5 6600HS Creator Edition` CPU and an `AMD Radeon Graphics` GPU. The results show that the `BORE` scheduler achieves an overall superior frame rate performance, while the `flash-k` scheduler demonstrates the greatest consistency in frame rate stability. However, the `bpfland-no-preempt` scheduler significantly lags behind in terms of FPS. Despite similar conditions, scheduling strategies clearly dictate performance, highlighting the complexity and impact of scheduler choice in system performance optimization.
