Linux 5.15 LTS To 6.17 Benchmarks: Four Years Of Kernel Improvement Net 37% Improvement On AMD EPYC
There have been some very nice Linux kernel optimizations over the past four years.
For anyone still running on a Linux ~5.15 era kernel is leaving a lot of performance still on the table with today's modern hardware.
Some of the video encoding/transcoding workloads can be quite sensitive to power management and more specific CPU frequency scaling behavior on different kernels. OpenAPV for instance shows Linux 6.17 delivering very nice improvements over the older kernels.
Linux 6.17 is looking to be in very good shape for the SVT-AV1 encoder performance on this AMD Milan server.
