Updated Kernel Benchmarks
Hi everyone,
I've been running some benchmarks using the new Ubuntu 22.04 image available here: https://distro.libre.computer/ci/ubuntu/22.04/
I've tested the Stock 5.19 shipped with this image, as well as some other kernels compiled by myself using Ubuntu 22.04. I used the mailine 5.18.12 kernel straight from the linux repository.
I've also compiled the same kernel including the following optimization flags:
CFLAGS="-march=armv8-a+crypto+crc -mtune=cortex-a53"I also tried a kernel version from librecomputer applying the same optimizations.
I've also tried running openSUSE images both for Leap 15.4 and Tumbleweed. I was unable to test the latter as no internet connection could be established.
I included some of the previous results I published with older images/kernels on the forum
As a summary, here are the average of the results:
The performance of the board has overall improved with the new images and kernels, but the extra optimizations don't carry any substantial performance increase, unlike with the older kernels. This could be due to differences between the compilers used ( gcc 9.3 vs 11.2) but it's hard to say since the package versions also changed between images.
