Hi @TechVortexZ, thanks for using Fast DDS.
Thank you for your patience, we have been focusing our efforts on the upcoming release of Fast DDS v3.0.0 over the past few days.
You can increase the sending period of heartbeats and acknack messages (WriterTimes configuration) to reduce the traffic. Please refer to this section of the documentation.
I am moving this issue to the Support focum according to the Fast DDS CONTRIBUTING guidelines.
