Summary
Yes (RSS,VMQ,VMMQ, Ipsec Offload, SR-IOV )
Details
(no major updates with WS 2019)
Server 2012 supports various functions that improve the networking performance by offloading operations to specialized hardware.
- SR-IOV (assign SR-IOV -capable network adapters directly to a virtual machine to maximize network throughput while minimizing network latency and CPU overhead.)
- Dynamic Virtual Machine Queue (D-VMQ) - essentially allows the hosts single network adapter to appear as multiple network adapters to the virtual machines, allowing each virtual machine its own dedicated network adapter, resulting in less data in the hosts buffers and an overall performance improvement to I/O operations. New in Server 2012: dynamically distributes incoming network traffic processing to host processors, based on processor use and network load. If network load is heavy, D-VMQ automatically uses more processors - with light network load, Dynamic VMQ uses fewer CPUs.
- IPsec Task Offload for Virtual Machines (uses hardware capabilities of server network adaptors to offload IPsec processing. This reduces the CPU overhead of IPsec encryption and decryption)
- Accelerating network traffic through Receive-side scaling and Receive Segment Coalescing
Note: In Server 2012 Virtual machine (VM) Chimney, also called TCP Offload, has been removed (incompatible with native NIC teaming in Server 2012) so TCP chimney will not be available to guest operating systems.
