I am having really slow network performance using Hyper-V on Windows Server 2012 R2.
1) I am using Broadcom NetXtreme Gigabit network adapters.
2) I have five Virtual machines that are using a single virtual switch that is hooked up to a single Gigabit NIC and these machines are not generating that much traffic.
3) This was not a problem when I was using Windows 2008 R2, only a problem when I reformatted from scratch and installed Windows Server 2012 R2.
4) When I ping the host OS (hyperv3), I can getting lots of latency (200ms), but when I check the network traffic over that, I am only getting (2.4 megabits upload and very small download rates). I am using Remote Desktop to connect, so that makes sense.
How can I troubleshoot this where this wasn't a problem before, but now it is? The OS has changed, the network cables and ports have not changed. Here is a screenshot showing my network info.
Can you help me troubleshoot the network performance issues? Thank you guys :)
