Performance Tuning

Latency

The interrupt coalescing settings are vital
●
ethtool -c eth3 to read , -C to set
●
Rx-usecs tells how often to service interrupt
●
NAPI may help as you can handle multiple interrupts

Also look at using TCP_NODELAY options
●
May help with latency but hurt throughput
●
“Nagles Algorithm” tries to fill packets in order to avoid overhead of
sending
