For `slab_nomerge`, it can lead to very slight increase of kernel memory. `init_on_alloc=1` has a almost no performance impact, it is under 1% and is usually within standard error, but there is bug with zfs that can make zfs slower. `init_on_free=1` can be measured and is around 7-20% under certain workloads, but in some workloads it does not impact performance. `randomize_kstack_offset=on` can sometimes increase performance by 1%, or decrease it by 1%, but Redis has been noticed to have performance reduced by 2%. `pti=on` mitigates meltdown, but has a very big performance impact. _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
