I use virio-scsi-single exclusively because of the hough performance
gain in comparison to virtio-scsi so I can concur to that.
I just benchmarked it in on a full-SSD-ZFS system of mine and got
reverse
results.
I used 4 cores, 512 MB-RAM (fio 2.1.11, qd32, direct, libaio) and this
varies:
Test | sequential 8K | randread 4K | randrw 4K 50/50
----------------------+---------------+-------------+----------------
virtio-scsi | 53k | 57k | 11k
virtio-scsi-single | 35k | 41k | 11k
virtio-scsi IO/Thread | 29k | 43k | 11k
virtio-scsi-single IO | 29k | 44k | 11k
So, what was your test environment? How big was the difference?
Are you running your ZFS pool on the proxmox node?
My benchmarks were made using ZFS over iSCSI.
