The XanMod kernel was tending to compete well for first place in the LevelDB storage benchmarks. The Liquorix kernel, which defaults to the BFQ I/O scheduler even when running off NVMe solid-state storage as used for this testing, tended to be the slowest.

Of the kernels benchmarked with the AMD Radeon RX 5600 series Navi graphics, there wasn't much difference in performance with the likes of the XanMod and Liquorix kernels. Linux 5.11 Git tended to be the slowest. The Linux 5.11 drops in performance there are due to the new AMD CPU frequency invariance support with Linux 5.11 as found out-of-the-box with the Schedutil frequency scaling governor... The AMD frequency invariance performance on Linux 5.11 still leads to many regressions if you are using Schedutil and not switching over to the "performance" governor or other alternatives.
