Abstract: This paper provides a list of WebSphere configurable options that can be used to reduce background processing within the application server and other components in the Network Deployment (ND) infrastructure (i.e. Nodeagent, DMGR, etc.) that consume CPU cycles when WebSphere would typically be considered “idle”. The paper details some of the tuning options, their implications and some recommendations which may help customer conserve resources during idle periods. Also provided are tuning considerations to minimize server startup times as CPU consumption during startup can have effects on other guests.
