@florent Florent, yes I do use NBD for all backups. And checking the backup log of the completed jobs I see that NBD is being used.

@manilx Running a test backup, one with NBD and then again without. Will report asap.

@florent Result of backup tests:

It may not be of any help, but wanted to add a little bit of info this anyway.
I'm seeing the same results on a set of Ubuntu 22.04 in my Threadripper based cluster. I didn't expect to see different results, since Threadripper is really just EPYC with some stuff turned off.
Specifically tested on a 16 core 1950X host and a 32 core 3970X host, both with 8 vCPUs on each VM, they topped out at 8 gigabit like most others are seeing.
Figured I'd add it in here.

Thanks! We didn't test on threadrippers yet, so it's useful info
