I'm having trouble with a 10 to 15 second delay time for discovery that I think I found information about how to adjust the configuration for RTI's implementation of DDS but I can't find the configuration in OpenDDS. How can I configure the equivalent of the following in OpenDDS?

The publication_reader, subscription_reader are of type DDS_RtpsReliableReaderProtocol_t. In these I would try modifying the attributes: heartbeat_suppression_duration (to 0 seconds, 0 nanoseconds), nack_period ( to 0 seconds, 500000000 nanoseconds).
The publication_writer and subscription_writer are of type DDS_RtpsReliableWriterProtocol_t . In these I would modify the late_joiner_heartbeat_period to (0 seconds, 500000000 nanoseconds).
If you see significant differences making these kind of changes it would indicate that some tunning could be the a good way to improve the performance.
