Although the ability to exchange large data buffers is a feature of Rendezvous software, it is good practice to avoid sending messages that are too large. For example, to exchange data up to 10,000 bytes, a single message is efficient. But to send files that could be many megabytes in length, use multiple send calls, perhaps one for each record, block or track. Empirically determine the most efficient size for the prevailing network conditions. (The actual size limit is 64 MB, which is rarely an appropriate size.)
