Actually, yes. The RSS feature can hinder transfers. It's a known issue.I
haven't seen this problem in a virtualized environment, therefore I would
suggest to disable the RSS/TCP Chimney feature on the host, and test it.
Depending on the NAS (is it a Windows machine or some third party box?), if
that option can be disabled on the NAS, I would disable there as well. If it
continues, disable it within the guests, too.
