You are invited to just read whats going on in the project. You write that you do not know how to fix it but you just assume it just easy for others.?Like I said in a previous post, I humbly admit that I don't know how to fix the problem myself (if I did I'd more than happily donate my time to repairing it and getting it committed into Proxmox GIT repo) but would like to see someone from Proxmox outline what's going on and what's been done so far and what the plan of attack is to get this issue under control.
this is not a fast and easy kind of problem:I want to make something clear here ... before we were users of Proxmox, we were users of Citrix XenServer. Why did we get off of XenServer? A couple of reasons ... XenServer had no built-in way to create VM backups and XenServer performed very poorly on disk IO. As you can see, our number 1 reason for moving to Proxmox was Proxmox provided excellent backups.
Why am I mentioning this? Proxmox needs to understand that the VM backups that has been a feature in Proxmox since the beginning sets them apart from the many other solutions making them more desirable. So, please, put some time into fixing the backup speed from Ceph as an old and counted on feature in Proxmox that I am sure we are not the only ones to appreciate. And appreciate that feature we do ... it is why we because subscribers, in order to give financial backup to the Proxmox team to help make sure they could continue to support the excellent feature set found in Proxmox currently ...NOT new features but the excellent features already found in Proxmox.

FreeNAS 11 with 10x 2TB SATA Disk connected via 10Gbe,@fips
What kind of NAS are you using? I only get about a third of what you are getting to your NFS (you showed 128 MB/s)
All those throughputs have to be on 10Gb ethernet but is the NAS a generic piece of hardware like a Dell with standards Linux on it or is it a Proprietary NAS solution?
Yes. As joke:Let me rise this topic up, please.
Is anybody could run backup faster than 40MB/s ?
