- Performance tuning is the improvement of system performance. Typically in computer systems, the motivation for such activity is called a performance problem, which can be either real or anticipated. Most systems will respond to increased load with some degree of decreasing performance. A system's ability to accept higher load is called scalability, and modifying a system to handle a higher load is synonymous to performance tuning. Systematic tuning follows these steps: 1.
* Assess the problem and establish numeric values that categorize acceptable behavior. 2.
* Measure the performance of the system before modification. 3.
* Identify the part of the system that is critical for improving the performance. This is called the bottleneck. 4.
* Modify that part of the system to remove the bottleneck. 5.
* Measure the performance of the system after modification. 6.
* If the modification makes the performance better, adopt it. If the modification makes the performance worse, put it back the way it was. This is an instance of the measure-evaluate-improve-learn cycle from quality assurance. A performance problem may be identified by slow or unresponsive systems. This usually occurs because high system loading, causing some part of the system to reach a limit in its ability to respond. This limit within the system is referred to as a bottleneck. A handful of techniques are used to improve performance. Among them are code optimization, load balancing, caching strategy, distributed computing and self-tuning. (en)
