Hello there, I have a 5 node PM clsuter, ceph is configured, each node has a 3.84 TB ssd for OSD and 1 nvme drive for WAL/DB usage. ceph network is on 10G link and proxmox managmend network is on a 1G link

CEPH benchmark is as below :

READ ~= 1000 MB/S
Write ~= 1000 MB/S


I create a Windows vm and now inside windows storage performance is too slow
Even installed virtio drivers, check emulate SSD, Enbaled write back cache but no difference

What can I do ?

Please tell me what kind of details you want that I post here for troubleshooting
