WebSphere Commerce default tunables
WebSphere Commerce Version 8 has two instance profiles, Test and Production. Each profile contains its own tunable values for the WebSphere Commerce and WebSphere Commerce Search 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.
