Slow Network for VM2 but fast for VM1

Hi:

I have a server running ESXi 5.5 with (2) VMs:

VM1: Virtual Machine Version 8, Windows Server 2012 R2 Standard, E1000E network adapter

VM2: Virtual Machine Version 10 vmx-10, Windows Small Business Server 2011 Stadard, E1000 network adapter

Both VMs are on the same VMNetwork and both are showing network adapters connected at 1Gbps.

If I run an Internet speed test from VM1, it comes back around 500 Mbps (customer has fast fiber Internet connection)

If I run an Internet speed test from VM2, it comes back at only 15 Mbps

Any ideas as to why VM2 connects to Internet so much slower?

Thank you!
