How do I set the sampling rate in kraken SDR source #3

How can I reduce the sampling rate in order to avoid the delay of the network? Also, if I have 5 streams of complex floats then the network speed (in Mbps) should be at least: sampling_rate 64 (size of complex float) 5. For example, for 2.4 MS I need 768 Mbps. Correct?

The sampling rate is set via heimdall. You can edit the sampling rate in heimdall_daq_fw/Firmware/daq_chain_config.ini. Might be wiser to just play with the decimation ratio though.

Calculations seem correct, this is why Gigabit ethernet is required if you are running Heimdall and DSP on separate machines.
