VMKernel Port versus Virtual Machine Port Group

I have ESXi v4.1 running on a small network.  I have 9 virtual machines running on this host.  Close to all of the throughput is being sent to and from internet hosts so bandwidth currently is not a big deal, however, I did notice copying data from VM to VM very rarely exceeds 100 mbps.  I have 1 gbps NICs on the VM's and only copying within the same ESXi host.  I'm beginning to wonder if it's my networking configuration.  I have one vswitch and within that one vswitch I have both a virtual machine port group and a VMKernel Port.  I have two NIC's in this server and each NIC has the ability to access the IP range assigned for this ESXi host.  Do I need to create another virtual switch and add a virtual machine port group to it and move my VM's in there?

The VM's are using Pro 1000 MT NIC's.  I'll swap out to VMXNET3's later this evening and will update the ticket.
