Receive Side Scaling (RSS) is a network performance optimization technology that allows network traffic to be distributed across multiple processors in a system, improving network performance and reducing processing time.
In a multi-processor system, RSS allows network traffic to be spread across all available processors, rather than being handled by a single processor. This results in faster processing times and reduced system load.
RSS is typically configured at the network adapter level, and can be enabled or disabled using PowerShell or the GUI.
To enable RSS using PowerShell, you can use the following command:
Set-NetAdapterRSS -Name "NetworkAdapterName" -Enabled $true
This command enables RSS on the network adapter specified by “NetworkAdapterName”. You can also disable RSS by setting the -Enabled parameter to $false.
To view the current RSS configuration for a network adapter, you can use the following command:
Get-NetAdapterRSS -Name "NetworkAdapterName"
This command displays the current RSS configuration for the network adapter specified by “NetworkAdapterName”, including the number of receive queues and the base processor number.
In addition to the network adapter configuration, RSS can also be configured at the operating system level using Group Policy settings. These settings allow you to control the number of RSS processors, the maximum number of receive queues, and other parameters related to RSS.
RSS is a useful technology for improving network performance in multi-processor systems. By enabling RSS and properly configuring it, you can ensure that network traffic is processed efficiently and without overloading any single processor.
