Situation
Virtual server running CIFS had normal file access times until it
was moved to a different VM host.
After the move file copies from the CIFS server to a standalone workstation were fine but copies up to the CIFS server were slow.

Resolution
Disabling the Large Receive Offload (LRO) setting in VMWare as
discussed in the VMWare document below addressed the issue on the
new VM host. Speeds to and from the server returned to
normal.
