In software engineering, a bottleneck occurs when the capacity of an application or a computer system is severely limited by a single component. The bottleneck has lowest throughput of all parts of the transaction path. As such, system designers will try to avoid bottlenecks and direct effort towards locating and tuning existing bottlenecks. Some examples of possible engineering bottlenecks are: a processor, a communication link, disk IO, etc. Any system or application will hit a bottleneck if the work arrives at a sufficiently fast pace. Tracking down bottlenecks (sometimes known as "hot spots" - sections of the code that execute most frequently - i.e. have the highest execution count) is called performance analysis. Reduction is usually achieved with the help of specialized tools, known as performance analyzers or profilers. The objective being to make those particular sections of code perform as fast as possible to improve overall algorithmic efficiency. ==See also== * Performance engineering * Profiling (computer programming) * Program optimization 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bottleneck (software)」の詳細全文を読む スポンサード リンク
