[PVE-User] Linux improvements for ceph and general running vm's

[Alexandre DERUMIER]

Hi,

do you want to improve latency or throughput ?


They are lot of thing to tune in ceph.conf before tuning network.
can you send your ceph.conf too ? (ceph cluster && proxmox nodes if ceph is outside proxmox)

ssd ? hdd ?
