Checklist for optimum performance of WCM 6.0 and 6.1.
This document contains a checklist of the key tasks required for tuning an existing Lotus Web Content Management environment.
It assumes adequate hardware and infrastructure is provided and does not cover capacity planning. It also does not go into detail of how to perform each task as this is covered in much more detail in the referenced documents and sources.
If you are experiencing performance problems or you are setting up a new environment, start by ensuring that all items in this checklist are checked. If there are still issues, further analysis would be required to identify the source of the problem. It could be that extra hardware is required, there are network problems or perhaps it is the way in which you are using WCM. Ensure you consider all parts of your environment. The database, LDAP server, firewalls, HTTP server, Portal servers, Web servers, policy servers for single sign-on and any back-end servers if your portlets access them.
When tuning individual systems, it is important to begin with a baseline, monitor the performance metrics to determine if any parameters should be changed and, when a change is made, monitor the performance metrics to determine the effectiveness of the change.
Applicable to version 6.0 and 6.1 only, does not apply to earlier versions
Thanks to Michael Wasmund for compiling the initial list
