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.
