Turning off SNP (Scalable Networking Pack)
The purpose of SNP is to reduce the processor load by delegating TCP-related processing to
the network adapter. SNP is made of the following three features.
・ TCP Chimney Offload
・ Receive Side Scaling (RSS)
・ Network Direct Memory Access (NetDMA)
Unfortunately, if the system in Windows® is used with SNP turned on, processing the
network may become unstable, or the network performance may be reduced when you use the
network in specific ways. This is why SNP is disabled in this equipment.
In Windows® 10, TCP Chimney Offload and Network Direct Memory Access are not
supported by OS, so that we set only Receive Side Scaling (RSS) for invalidity.
