Source Server Datastore speed, network speed, Destination Server Datastore speed, all contribute to the speed of transfer.

Data transfers can be slow.

Sometimes, it can be quicker, to move VMs to NFS datastore, and from NFS datastore to server local disk, using NFS and Jumbo Frames.

is there any setting for ESXI network config ?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
You can check if the network cards are set to the correct speed and duplex settings.

or you could build a trunk network, e.g. two bonded 1GBe nic ports.
