-Dcom.ibm.CORBA.BufferSize

This system property sets the number of bytes of a General Inter-ORB Protocol (GIOP) message that is read from a socket on the first attempt.

-Dcom.ibm.CORBA.BufferSize=<bytes>
Where <bytes> is in the range is 0 - 2147483647. The default size is 2048. A larger buffer size increases the probability of reading the whole message in one attempt. Such an action might improve performance. The minimum size that can be used is 24 bytes.
