I have read through a few posts on diagnosing performance, but wondering if I can get some help myself as I am having trouble.
Most of our job are backing up using NBD mode, and I can't seem to figure out why.
The majority of our backups report like this: 9/13/2018 8:34:31 PM :: Load: Source 98% > Proxy 15% > Network 4% > Target 0%
I would say on average we are seeing a processing rate of 20-30MB/s
So I would like to tweak these as best I can to see if I can get better backup performance. Here is a little about our setup.
we are running 3 VMs, each on its own host. One server is a Veeam server the other two setup as proxies. Each server has 8 vcores setup and 24GB of RAM. The datastore is a Nimble, and they back up to a synology but that does not appear to be the performance issue. I have seen the source as low as 75% on one job, but most are in the 90%+ range. Each server is setup with iSCSI connections to the SAN, but that doesn't appear to be used. I think we need the enterprise plus license to take advantage of that.
I also can't seem to figure out why they don't hotadd. 1 or 2 jobs will. I saw only one backup that had an error about hot add. The rest just showed in the console as NBD. Let me know if this should be a ticket. I will likely enter one anyway, just in case, but thought I would reach out to the community. I am trying to figure out if it is a configure issue, hardware issue, me issue

I would like to make sure I understand what is going on here and understand Veeam at a more fundamental level. Like the Load/Performance and what it should look like. I have been pouring over the docs a lot!
Thanks,
