[Version 5.0.1 and later]Security tuning tips for z/OS

As a general rule, two things happen when you increase security: the cost per transaction increases and throughput decreases.

By default, WebSphere for z/OS runs with security off. With security turned off there is virtually no overhead. However, we recommend that you run with security enabled, even though the runtime will always incur a small price to collect and carry the security credential information for users and the server. Compared to no security, global security for a sample application took about 13%. Compared to no security, java2 security took about 18%. Enabling a single role on every method in a sample application with global and java2 security costs about 38%.
