Vdisk_fileio is a bit dangerous in write cache mode. Also, for some reason, object size of 16MB for RBD does better with VMWare. Storcium gives you a choice for each LUN. The challenge has been figuring out optimal workloads under highly varied use cases. I see better results with NVMe journals and write combining HBAs, e.g. Areca.
