RSSv2 for Hyper-V
In Windows Server 2019, Microsoft added support for Receive Side Scaling
version 2 (RSSv2) with Hyper-V (RSSv2 per vPort).
RSSv2 Description
Compared to RSSv1, RSSv2 decreases the time between the CPU load
measurement and the indirection table update. This feature prevents slowdown
during high-traffic situations. RSSv2 can dynamically spread receive queues over
multiple processors much more responsively than RSSv1. For more information,

scaling-version-2-rssv2-
RSSv2 is supported by default in the Windows Server 2019 driver when the
Virtual Switch RSS
option is also enabled. This option is enabled (the default),
and the NIC is bound to the Hyper-V or vSwitch.
