Title:
Kernel linux-image-5.19.0-32 regression, compile speed down by 33%
Status in linux package in Ubuntu:
Expired
Bug description:
I just yesterday and the day before made some benchmark tests for a
comparison between ext4 and zfs. I ran repeated builds of a large
software package and it always came out to 45s. Now today I ran the
same test a few times and it was always 60s. I noticed that today an
update ran and that kernel 5.19.0-32 was installed. So just now I
booted back to 5.15.0-60-generic:amd64 and ran the test again: back to
45s.
I am running Ubuntu 22.04.1 LTS on a AMD Ryzen 3970X with 128GB RAM
otherwise there is nothing very special going on. I ran the tests on
ZFS and ext4, it makes no difference.
To reproduce, I would think that compiling any decent sized software package
one on 5.15 and then on 5.19 whould yield the same results.
