Hi, Thx for your answer @Alwin. In fact, 1) I just would like to know the random write iops I could reach in the VMs of my Proxmox cluster and 2) I would like to understand why the option --fsync=1 lowers the perfs to this point. I admit, I probably need to learn more about fio (and I/O on...

Hi Alwin and thanks for your advice concerning the principle of a baseline comparison. In fact, I don't know exactly the performance I can expect but I have made another fio benchs (I have read some docs about fio) and I have the feeling that my new benchs are not really good as regard my...

Hi, I have made an Proxmox cluster version 5.2 with a ceph storage (internal to Proxmox) and I have made a benchmark in a VM with fio. My problem is: 1. I'm not expert at all in benchmarks (and in fio) and I'm very cautious concerning benchmarks, maybe my benchmark is not relevant at all. 2. I...
