Hi, I'm testing RTI Connext DDS java version on Windows XP.
I calculated RTT(round trip time) of reliable message and founded that on initial RTT takes 1~2 sec (average takes 2 ms ) during 9 sec.
Reliability QoS is set as reliable for the DataWriters & DataReaders, and also set the asynchronous publish mode with default flow controller.
Sender sends 1600bytes sized reliable data every 50ms and 8000bytes sized unreliable data every 10ms.
I guessed that data sending parts take much time at some interval.(See the attached file.)
This situation happenes only in java program ( I tested same program in C++ and C# but they don't appear this situation.)
I want to know why this situation happenes and what else configuration setting I have to do.
Thanks in advance.

This turned out to be an issue with the configuration of the Java JVM.
