Thank you @RobertCNelson, that is what I was looking for.
A packet length of ~2000 bytes could be a big help in my particular case.
However, both ip and ifconfig commands return an error if I attempt to set the packet size >1500.
ifconfig eth0 mtu 1501 up
SIOCSIFMTU: Invalid argument
ip link set eth0 mtu 1501
RTNETLINK answers: Invalid argument
Am I missing something here?
Thank you again.
