I've been using the 5.0 kernels locally compiled and optimized for my hardware with bfq enabled. I don't have multi thread hardware. The performance has been comparable to cfq, or slightly worse. Subjective. And there could be other software changes affecting this. I've recently also started using the gcc kernel-stack plugin to clean stack on return from kernel calls, and didn't really notice any effect on performance in normal usage. _______________________________________________ kernel mailing list -- kernel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to kernel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/kernel@xxxxxxxxxxxxxxxxxxxxxxx
