Is the channel using compression?
If the channel is using compression, this will add to the time spent processing
messages.
If only one compression algorithm is being used, do the following:
- In the output of the command DIS CHSTATUS(QM1.TO.QM2) ALL,
check the COMPTIME field.
These indicators show the time spent during compression
or decompression.
- If the chosen compression is not reducing the amount of data to send by
the expected amount, then change the compression algorithm.
If multiple compression algorithms are being used, do the following:
- In the output of the command DIS CHSTATUS(QM1.TO.QM2) ALL,
check the COMPTIME, COMPHDR, and COMPMSG fields.
- Change the compression algorithms specified on the channel definition,
or consider writing a message exit to override the channel's choice of compression
algorithm for particular messages if the rate of compression, or choice of
algorithm, is not providing the required compression or performance.
