  11. 11. Slide 11 | PROPRIETARY AND CONFIDENTIALOther Tuning Tips• RSS Spreading– Changing the default RSS spreading so that the card uses an RX queue per CPUcore. This is done by setting the driver’s module parameter rss_cpus=cores. Seesection “Receive Side Scaling (RSS)” on page 193-194 for more details. If youcan, we also suggest you disable the irqbalancer service before doing this, as theirqbalancer tends to undo the good work of spreading the networking interruptsover the available CPU cores (see page 196)• Enable LRO– Double check LRO is enabled using ethtool. As mentioned RHEL 6 libvirtddaemon can cause this to be disabled. See “TCP Large Receive Offload (LRO)”on page 191-192 for details of LRO and how to change RHEL6 behaviour• Interrupt Moderation– IF (and only if) you think the benchmark is latency sensitive then we suggestdisabling interrupt moderation. The driver by default uses adaptive interruptmoderation and tries to tune based on traffic patterns. However, if you know youhave a ping/pong – transactional app then helps to disable this completely (seepage 189 – “ethtool –C <ethX> rx-usecs-irq 0 adaptive-rx off”). BUT if you arestreaming large blocks of storage data between the servers then don’t do this - thedefault is best.
