#define ACE_DEFAULT_BROADCAST_PORT 20000

#define ACE_DEFAULT_CDR_BUFSIZE 512

| Control the initial size of all CDR buffers, application developers may want to optimize this value to fit their request size

#define ACE_DEFAULT_CDR_EXP_GROWTH_MAX 65536

| Stop exponential growth of CDR buffers to avoid overallocation.

#define ACE_DEFAULT_CDR_LINEAR_GROWTH_CHUNK 65536

| Control CDR buffer growth after maximum exponential growth is reached

#define ACE_DEFAULT_CDR_MEMCPY_TRADEOFF 256

| Control the zero-copy optimizations for octet sequences. Large octet sequences can be sent without any copies by chaining them in the list of message blocks that represent a single CDR stream. However, if the octet sequence is too small the zero copy optimizations actually hurt performance. Octet sequences smaller than this value will be copied.
