Yes, I had to tune some settings on PostgreSQL. Especially on: synchronous_commit = off I have a default RBD settings. Do you have any recommendation? Thanks, Gencer. On 19.10.2020 12:49:51, Marc Roos <m.roos@f1-outsourcing.eu> wrote:

In the past I see some good results (benchmark & latencies) for MySQL and PostgreSQL. However, I've always used 4MB object size. Maybe i can get much better performance on smaller object size. Haven't tried actually.

Did you tune mysql / postgres for this setup? Did you have a default ceph rbd setup?
