Eric,
ZCIOWAIT indicates VTAM terminal control wait. My first guess is that
you are function shipping to another CICS region using VTAM connections
between the regions and you are looking at the front-end transaction.
In this case this is a normal situation. As for optimizing, it is
really dependent upon the function the back-end region. Improve the
task in the back-end region and you will shorten the wait in the front-end.
