Memory management is the process of memory allocation for program execution and memory reuse after some of the allocated memory is not used anymore. In Java, this process is called garbage collection (GC). The effectiveness of GC affects two major application characteristics—responsiveness and throughput.
Responsiveness is measured by how quickly an application responds to the request. For example, how quickly a website returns a page or how quickly a desktop application responds to an event. Naturally, the lower the response time, the better the user experience, which is the goal for many applications.
Throughput indicates the amount of work an application can do in a unit of time. For example, how many requests a web application can serve or how many transactions a database can support. The bigger the number, the more value the application can potentially...
