Could you confirm that transport mode used for backup job is "hot-add"?
It should be written in the job`s logs as:
Using backup proxy VMware Backup Proxy for disk Hard disk 1 [hotadd]
If the transport mode is hot-add, what is your bottleneck statistics?
Thanks!

I try virtual appliance and when I look on the proxy I see 2 disks mount on the proxy. The first one are the source disk and the second one the destination.
In my case both are on different storage. And with windows perfmon I monitor the read write on both and I got 20 mb/s.
After this test I add 2 disks on the proxy, don't have choice to format in NTFS here. And I copy file between them... I've got 200 mb/s.

I don't understand... I create the same patern.

I don't find any line looking like yours. The closes one are:
Using backup proxy proxy1 for [VolB1] printsvr/printsvr.vmdk

but I found lot of "hotadd" in the log. [HotAddDisksRemover]

Please work with our support to help you with ensuring hot add is used on both sides, this will allow Veeam job to complete faster than VMware clone.

Here the support answer:

"Veeam Copy is a full block for block and target is always thick provisioned, whereas VMware Clone only copies used blocks and can maintain disk format. Obviously these two can be compared as they are not the same thing in the slightest."
