Slow Network Performance Between Host & Guest

Running a Windows guest on a Linux Host and using Samba to share files from the host, I have witnessed extremely slow file transfer performance. I have seen this on multiple stations and multiple situations.

ethtool -K eth0 tso off

and restart Samba. This worked for me, and I also put the line in the Samba start script.

Also suggested:
ethtool -K eth0 tx off
ethtool -K eth0 sg off
