-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Now that WPQ has been merged in master, please test it out in your environments. There have been performance improvements across the board in my testing with SSDs having the largest gains and it would be great to get some others' review as well. There was discussion to potentially make this the default queue for Jewel, so the more testing the better. To enable the WPQ and adjust the priority cutoff, use the following in ceph.conf (by default it uses the PrioritizedQueue): osd_op_queue = wpq osd_op_queue_cut_off = low It does require an OSD restart (not a run time tuneable option) to change the queue/cutoff.
