Allows the network driver to wait for enough packets of information to be generated before sending them, lowering the necessary number of times the driver has to send an interrupt message, which in turn lowers the CPU latency. locate D0 Packet Coalescing or Packet Coalescing and under Value, select Disabled from the drop-down. REASON(S) TO TURN OFF: Acts like a packet buffer for sending interrupts. If your network adapter has the following adapter settings, set them as follows: Disable Receive Side Scaling. Press Windows + R to get the Run console. Disable Flow Control - It sounds counter-intuitive to disable flow control, but TCP has it's own flow control mechanism and if an occasional UDP packet gets dropped, it has no appreciable impact on the performance of the radio.

However, as the incoming packet rate increases, the device driver. Without some form of interrupt moderation logic on the adapter, this might lead to an interrupt for each incoming packet. Receive Segment Coalescing (RSC) allows the NIC to coalesce multiple TCP/IP packets that arrive within a single interrupt into a single larger packet (up to 64KB) so that the network stack has to process fewer headers, resulting in 10% to 30% reduction in I/O overhead depending on the workload, thereby improving throughput. For receive operations, interrupts typically inform the host CPU that packets have arrived on the devices input queue. These calls wake up the processor, memory and other system components from a lower. Typically, when a packet arrives at a server, DMA calls are made to transfer the packet within the server. DMA Coalescing Another power management technology that can reduce power on the server platform is DMA Coalescing (DMAC).
