Vista - Network Adapter & Legacy Network Adapter

My Hyper V host 3 vm's and has 2 physical nics.

I setup 1 nic as an external virtual network, and I unselected "Allow
management operating system to share this network adapter.

I want to use this virtual switch for all 3 vm's.

So I setup each machine with a Network Adapter connecting to this virtual
switch, the problem is each of the vm's networks run very slow. For example;
when remote desktop into one of the vm's and I click the start button it well
take several seconds before it appears.

But if I use Legacy Network Adapters instead of Network Adapters in all vm's
connecting to the same virtual switch their networking works as expected,
fast with no delays.

Can someone explain what I may be doing wrong since Network Adapters are
suppose to work better and faster then Legacy Network Adapters.

forums.
