Hi, I've got some general questions about topics in ROS1. Do you have any tips or tricks on how to tune Linux (Ubuntu 18.04) to act better with topics? I want to reduce message transport time as much as possible.

I know that I can use nodelets to have zero-copy time, but I am made use of nodes instead.

Best regards.

It depends on your requirements IMHO, if you have some realtime requirements then adding RT-Linux patch would help along with realtime-tools pkg for publishing and on subscription side you could use an option like "TransportHints().tcpNoDelay" (API)
