Thanks for the suggestion. I indeed did a run before disabling the C/P states in the BIOS. But unfortunately I didn't keep the results. :/ As far as I remember though, there was a visible improvement after disabling them. I will have a look, once I have some time to do some more benchmarks. -- Cheers, Alwin _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
