Workstation 9 - Slow network performance between host and guest

I am running windows 8 on the host and installed Workstaion 9 trial. Then installed windows 8.1 as a guest system.

I am getting slow, really slow network between the two.

If i send files to and from the guest with another computer, transfers are normal, but if I try same files between host and guest they are really slow.

I am using a Bridge connection.

I have read elseware to disable the following on the host adapter:

Large Send Offload v2 (IPv4)

Large Send Offload v2 (IPv6)

But that did not help.

Thoughts?
