Source Server Datastore speed, network speed, Destination Server Datastore speed, all contribute to the speed of transfer.<br />

Data transfers can be slow.<br />

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

You can check if the network cards are set to the correct speed and duplex settings.<br />
<br />
or you could build a trunk network, e.g. two bonded 1GBe nic ports.

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
