Garbage collection and performance tuning both are integral components of application behavior on Java platforms, and a variety of collection techniques exist. They all involve trade-offs, balancing requirements for throughput, space, responsiveness, and available memory across varying levels of scale.
The key drawback of most performance tuning options is the need for long application pauses, a result of the inevitable requirement to compact the heap to free up space. A number of strategies can be used to delay these events, but compaction is inevitable for all collectors available on the market, except Azul C4, which deploys a strategy that altogether avoids pauses.
By developing an in-depth understanding of performance tuning, Java developers can improve scalability, reliability, and application performance, and make more informed choices about garbage collection (GC) options, which can result in measurable enhancements in application performance.
