In software, a throttling [[process (computing)|process]], or a throttling controller as it is sometimes called, is responsible for regulating the rate at which application processing is conducted, either fixedly or dynamically.
For example, in high [[throughput]] processing scenarios, as may be common in online transactional processing ([[OLTP]]) architectures, a throttling controller may be imbedded in the application hosting platform to balance the application's outbound publishing rates with its inbound consumption rates, optimize available system resources for the processing profile, and prevent eventually unsustainable consumption. In, say, an [[enterprise application integration]] (EAI) architecture, a throttling process may be built into the application logic to prevent an expectedly slow end-system from becoming overloaded as a result of overly aggressive publishing from the [[middleware]] tier.
== Thermodynamics ==
In thermodynamics, a throttling process, also called a [[Joule-Thomson effect|Joule-Thomson process]], is a type of [[isenthalpic process]] where a liquid or gas is cooled as it passes from a higher pressure state to a lower pressure state.
This process is especially very important in field of refrigration where refrigrant passes from higher pressure to lower pressure alomg with the corresponding decrease in temperature.The slope of an isenthalpic curve is called the joule thomson coefficient
