Optimizing Garbage Collection for Performant Programs
The key to building performant garbage collected programs lies in understanding how to adjust settings to optimize program behavior. Different garbage collectors have varying settings that can be challenging to tweak for optimal performance. The design of the camel garbage collector simplifies this process by offering a straightforward adjustment that either increases memory usage for faster performance or decreases memory usage for slower performance. Another consideration in garbage collection is the trade-off between responsive programs and pauses. While tracing collectors may pause the program to scan everything, reference counting collectors work incrementally. However, reference counting collectors also face challenges when decrementing counts to zero, requiring immediate and synchronous collection of a large amount of data.
