Interrupt Moderation. I'm running Vista Home Premium 64 and a Netgeat WGR614 router, I'm confused with these two settings: Priority & VLAN Flow Control currently Priority & VLAN are both enabled, and Flow Control is set to TX and RX enabled. The hardware can handle many more small packets per second however, and for this reason an adaptive interrupt moderation algorithm was implemented. The command is useful for. ARP Offload Auto Disable Gigabit Energy Efficient Ethernet Flow Control Green Ethernet Interrupt Moderation IPv4 Checksum Offload. Flow Control - Enabled. Enables/disables adaptive interrupt moderation.

While RDMA-based applications greatly reduce CPU utilization and can eliminate system interrupts, traditional Ethernet needs a lot of optimized tuning to accomplish the same results. Interrupt throttling control to limit maximum interrupt rate and improve CPU usage Flow Director (16 x 8 and 32 x 4) 128 transmit queues Receive packet split header Receive header replication Dynamic interrupt moderation TCP timer interrupts Relaxed ordering Support for 64 virtual machines per port (64 VMs x 2 queues). int_coal_threshold (R/W) Interrupt coalescing threshold in number of command comple- tions. The Intel® Ethernet 700 Series network adapters address the demanding needs of the next-generation agile data center by providing unmatched features for both server and network virtualization, flexibilityfor LAN and. Common problems are DMA alignment restrictions where the beginning of a frame must fall on some specific address granularity which is coarser than the general CPU platform alignment. Next is your ethernet/wifi or NIC (Network Interface controller) Now most of this is going to apply to Intel based NICs but you should be able to figure it out for other vendors I like to keep CPU cycles as free as possible so I make sure to enable all offloads for UDP and TCPchecksums,etc. All it does is add extra overhead since you waste time with extra context switches back to yourself in between servicing packets. Performance Effects of Interrupt Throttle Rate on Linux Clusters using Intel Gigabit Network Adapters Abstract: Summary form only given. 1BestCsharp blog 4,104,884 views. What is your kernel time and total CPU time while doing the transfer? CPU issues are common when you're talking about 10Gb rates. The dedicated input/ output (I/O) bandwidth of PCIe ensures priority performance - without bus sharing - for Gigabit Ethernet connectivity in Category-5 networks.
