Comment 17 for bug 1969482

I need an advice please:

Does this mean we need to switch to zfs-dkms instead of stock zfs to get the fix? Is this the long-term recommended solution?

As it stands today, with stock zfs, the zfs-kmod version is 2.1.2 hence contains the performance regression. Example on an up-to-date Jammy:

# zfs --version
zfs-2.1.4-0ubuntu0.1
zfs-kmod-2.1.2-1ubuntu3
