The IBM® CICS® Performance Series is a collection of IBM Redpaper™ publications that are focused on the performance of CICS and written by members of the IBM Hursley CICS development community. The topics are chosen based on feedback from CICS customers, with the goal of expanding your understanding of the rich features that are offered by the CICS Transaction Server (CICS TS) product portfolio.

This latest publication, A Processor Usage Study of Ways into CICS, focuses on processor usage costs and documents the results of tests that are performed to assess some widely used methods of getting data in and out of CICS.
