Data compression may provide the best throughput and line utilization. CA XCOM Data Transport compresses any group of four or more blanks or binary zeros and sends out a compressed data stream. The data compression feature should provide maximum savings when transmitting text files that usually have a large percentage of blank space. However, data compression also increases the CPU usage for each data transfer and may, in some cases, create additional overhead. The new zlibn compressions have been developed for maximum throughput with minimum overhead.
To decide whether the use of data compression may be helpful (especially for bulk data transmission), send a small sample of the data twice, once with data compression and once without. Check the XCOM.LOG file (located in your CA XCOM Data Transport install path) for the character per second throughput.
