Hello Colin, this looks promising for my arc_prune spinlock contention problems:
https://github.com/openzfs/zfs/pull/10331 with some background here: https://github.com/openzfs/zfs/issues/7559 This might have a simple ~dozen line fix! It's not yet reviewed by the openzfs gurus but it sure *looks* plausible to me. I tried to bodge this patch into the dkms module you gave me for my other zfs problem, but I have no confidence in my work -- I tried to reduce the number of arc_prune threads but failed, so I'm skeptical if I was able to change anything anyway. (I'm finding dkms to be *very* confusing.) Any chance I can ask you to put together a dkms with this patch? I'd trust your work way further. :) Thanks -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1814983 Title: zfs poor sustained read performance from ssd pool To manage notifications about this bug go to: https://bugs.launchpad.net/zfs/+bug/1814983/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
