Hello,
I posted more benchmark results in this article:
https://fedoraproject.org/wiki/Category:Changes/OptimizeSquashFS
In short, bigger block size and higher compression ratio does not increase
the installation time for Fedora Workstation. I saw the opposite effect.
The Zstd compression performed worse than XZ in the compression test. On
the other hand, 40% lower installation time for Zstd, was documented. Along
with the CPU consumption 37% lower.
All installation tests were performed from and to local NVMe storage. Which
I consider far from real life scenario.
I plan to perform more testing, with slower installation media, and will
post the results next weekend.
I did not evaluate CONFIG_SQUASHFS_DECOMP_MULTI this weekend.
Many thanks for doing this testing. It's really appreciated as well as
driving this change forward. :)
