          On further testing it looks like MB-31105 causes this slowdown
          On a lower level, using the protocol tcp4 / tcp6 in net.Listen on windows is what causes the throughput degradation.
          This issue is specific to windows and is not seen on other platforms.

          Possible actions moving forward -
          1. Disable the fix just for windows.
          2. For IPv6 enabled - use the fix and document the degradation. For Ipv4 (default) use tcp protocol.
          3. Disable the fix for all platforms.

          This looks like a Golang issue. Have opened a bug for go - https://github.com/golang/go/issues/40243
