VMware document to reference that explaining this limitation:

vSphere is limited to 32 mb connection buffer

"
vSphere 5 and vSphere 6
	
to an ESXi host
	
Limited by a transfer buffer for all NFC connections, enforced by the host; the sum of all NFC connection buffers to an ESXi host cannot exceed 32MB.
52 connections through vCenter Server, including the above per-host limit.
"
