> It can be turned off during boot by using init_on_alloc=0 kernel parameter. So any user who is affected by this performance issue can mitigate that by disabling the hardening option, after considering its possible consequences.
And one can find the root cause only by test and compare with other kernel with init_on_alloc=0 by default, and iterate over all config options and kernel changes. Looks like another point to add into "someone's performance guide", because it can't be mitigated easily via kernel interface changes from module's side (AFAIK). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1862822 Title: init_on_alloc=1 causes big performance regression for ZFS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1862822/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
