DPC Time and Its Bindings
- What is DPC?
- Why does it have such an impact on performance?
- How does NT bind the DPC time? HKEY_LOCAL_MACHINE\SYSTEM\CURRENT_CONTROL_SET\SERVICES\NDIS\PARAMETERS\ProcessorAffinityMask:REG_DWORD:0xfffffff
- How can we influence or change the binding and what impact does it have on VP’s user time and context switches?
- Is it better to distribute DPC on physical CPUs or leave it bound to a CPU (Default behavior)?
