[PVE-User] CEPH performance

[Marco Bellini]

Dear All, 
I'm trying to use proxmox on a 4 nodes cluster with ceph. 
every node has a 500G NVME drive, with dedicated 10G ceph network with 9000bytes MTU.

despite off nvme warp speed I can reach when used as lvm volume, as soon as I convert it into a 4-osd ceph, performance are very very poor. 

is there any trick to have ceph intro proxmox working fast?

thank you everybody for any advice.
