Brendan Gregg has written several good talks and documents about various Linux performance measurement tools. You might want to see what the kernel is doing when you see sluggish behavior. http://brendangregg.com/linuxperf.html It does require some deep spelunking into the kernel internals, but it is actually quite amazing what the kernel has for monitoring its activities. I use it quite often to debug filesystem behavior, just poke around /sys/kernel/debug/tracing/events/. https://www.kernel.org/doc/html/v5.8/trace/events.html From my experience, as an end user providing feedback, the kernel developers really like it when you can point out a particular syscall from the trace output that is misbehaving. -- Jonathan Billings <billi...@negate.org> _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org 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/users@lists.fedoraproject.org
