Tuning Parameter	How?
MTU Size to maximum supported by network	Leave at default
Interrupt moderation	Disable with: ethtool -C <ethX> rx-usecs-irq 0
TCP/IP Checksum Offload	Leave at default
TCP Segmentation Offload	Leave at default
TCP Large Receive Offload	Disable using sysfs: echo 0 > /sys/class/net/ethX/device/lro
TCP Protocol Tuning	Leave at default, but changing does not impact latency.
Receive Side Scaling	Application dependent
Interrupt affinity & irqbalance service	Stop irq balance service: /sbin/service irqbalance stop Interrupt affinity application dependent
Buffer Allocation Method	Leave at default
PCI Express Lane Configuration	Ensure current speed (not the supported speed) reads back as "x8 and 5Gb/s" Or "x8 and Unknown"
CPU Speed Service (cpuspeed)	Disable with:/sbin/service cpuspeed stop
Memory bandwidth	Ensure Memory utilizes all memory channels on system motherboard
Intel QuickData (Intel chipsets only)	Enable in BIOS and install driver: modprobe ioatdma
