WebSphere Commerce default tunables

WebSphere Commerce has two instance profiles, Test and Production. Each profile contains its own tunable values for the WebSphere Commerce Java virtual machines (JVM) and WebSphere Application Server caches. These values are in place to provide a standard base level of performance from which to operate, or tweak for improvements to individual configurations.

WebSphere Commerce uses containerization. To ensure that your tuned settings persist in subsequent container instances, follow the procedure described in Building custom Docker images based on customization packages.
