[ceph-users] How OSD encryption affects latency/iops on NVMe, SSD and HDD

Hi all, For those who use encryption on your OSDs, what effect do you see on your NVMe, SSD and HDD vs non-encrypted OSDs? I tried to find some info on this subject but there isn't much detail available. From experience, dmcrypt is CPU-bound and becomes a bottleneck when used on very fast NVMe. Using aes-xts, one can only expect around 1600-2000GB/s with 256/512 bit keys. Best, Tri Hoang
