• Optimized Interrupt Moderation. When this configuration is set to optimize, the driver automatically
and continuously determines the best Target DPC (deferred procedure call) Rate to use based on the
current network conditions. When this configuration is set to manual, the user can select a Target
DPC Rate and the driver adjusts the adapter's interrupt setting to achieve that DPC rate. Changing
this setting may improve performance for some configurations.
• Target DPC Rate. Determines the desired DPC rate. The driver adjusts the adapter's interrupt
moderation setting dynamically based on network conditions to achieve the desired DPC rate. This
configuration is valid only when "Optimized Interrupt Moderation" is set to manual.
