3.2 When to plan and tune your system Everyone wants value for their money and tangible benefit for the cost of performance tuning. When should you plan and tune your system for performance? You need to plan and tune your system in any of the following situations: Planning and designing a new system Keep the system performance goal in mind during the initial planning and designing phase of a system. Many performance problems arise from poor planning and poor design. It is hard to tune a system to correct design problems. Installing a new system A newly built system requires initial tuning for maximum performance before going into production. In most of the cases, however, this system might already be in production because of the difficulty of generating user workload artificially and not being able to predict real user workload and work patterns. Ideally, the number of users and workload is still growing and has not reached maximum expected capacity. This allows tuning before system response times become unacceptable. Regular maintenance Regular periodic monitoring and tuning should be standard practice. It may be a good idea to perform a system performance review on a quarterly, bi-annual, or yearly interval. Be proactive in identifying problem machines, applications, and systems. This will help avoid potential crises that halt business activities. User complaint or a crisis just occurred Users are complaining or a crisis in performance or response time just occurred. Based on the severity of the performance problem, you might need to identify the bottleneck or issue immediately, recommend and run a solution that might include tuning, then work out procedures for avoiding these types of issues in the future. Upgrading an existing system or changes in workload New resources might be added to the existing system or to replace some existing resources; additional workload might be demanded of the existing system. For example, you need to add a new Resource Manager to accommodate new and additional digital content. The current system must go through tuning activities for the new system configuration.
