Optimization Of Network Parameters

To improve performance, some system parameters may have to be adapted on the target system. For some of them, you may need to have administrator privileges.

• An MTU of 9000 (at least 8000 should be used)
• Via sysctl, some more optimizations could be made:

  sudo sysctl -w kern.ipc.maxsockbuf=8388608 // or more if possible
  sudo sysctl -w net.inet.udp.maxdgram=9216
  sudo sysctl -w net.inet.raw.recvspace=16777216 // or more if possible
  sudo sysctl -w net.inet.udp.recvspace=7454720 // or more if possible

  Note

  These changes are only valid for the running session and have to be set after each start of the system
