Updated dds version from 1.5.0 to 2.10.1, I got the memory reduced on vxworks platform

[zzhywzq]

There is a demo based on cyberRT, the memory reduced 40M when I replaced the new dds library. How dose it take effect?

1. before: rtps1.5.0, memory 80M was used.
2. after: rtps2.10.1,memory 40M was used.

There has been efforts to reduce the memory consumption of user's applications using Fast DDS. Nevertheless, it is so long since FastRTPS v1.5.0 has not been supported that I can hardly help you. After upgrading is everything working as you expected? If so, I would not be concerned about the memory reduction.

It works fine, but it makes great sense to lower the memory when VxWorks system resource is limited.
