Thanks for your comment. I did a fresh run just now. Roughly:
- local SSD: fio halved, ioping doubled
- cloud volume: ioping doubled
Not great.
I read these Hetzner benchmarks as a volume has 10x slower performance than its local SSD. :-(
Thank you so much for this. I wish Hetzner made it more clear that their volumes SUCK! This was causing so many problems for our Postgres cluster hosted on Cloud using their Volumes.
Did you find a better solution? Heaving the same Problem with MySQL.
