IBM CICS Performance Series: Web Services Performance in CICS TS V5.3
z Systems Software

Redpaper, published 20 Jan 2016, last updated 21 Jan 2016

This IBM® Redpaper™ publication describes a set of benchmarks comparing an IBM CICS® web services workload running in various configuration scenarios. This paper starts with an IBM CICS Transaction Server (CICS TS) V5.2 benchmark running on an IBM zEnterprise® EC12 (zEC12), and shows the performance characteristics of that same workload running on a similarly configured IBM z13™ (z13). We then compare the same workload running on IBM CICS TS V5.3 and demonstrate the performance benefits of CICS TS V5.3 as compared with CICS TS V5.2 for various scenarios, including Secure Sockets Layer ...
