The below given link says that the driver has been using the BLK-MQ interface for a while but not actually multiple queues until now with having a queue per-CPU. A change to not hold onto caps that aren't actually needed. These improvements and more can be found as part of the Ceph changes for Linux 5.7, which should be released as stable in early June. https://www.phoronix.com/scan.php?page=news_item&px=Linux-5.7-Ceph-Performance My question is: Is it possible that through Ceph FS (Filesystem in User Space) I can develop a multi-queue driver for Ceph? Asking because this way I can avoid kernel space. ( https://docs.ceph.com/docs/nautilus/start/quick-cephfs/) Looking forward for some help BR Bobby _______________________________________________ ceph-users mailing list -- ceph-users-a8pt6IJUokc@public.gmane.org To unsubscribe send an email to ceph-users-leave-a8pt6IJUokc@public.gmane.org
