To many developers, garbage collection is black magic. Accordingly, there are is a lot of conflicting advice about what is good or bad for the garbage collector. In this talk, I look at how garbage collection is implemented in the HotSpot VM, and techniques for writing programs that exhibit good garbage collection behavior. Surprisingly, many of these techniques coincide with writing good, clean code.
This presentation covers: - Basics of garbage collection in HotSpot - Where the performance costs are in garbage-collected systems - Coding techniques for reducing GC costs - Finalization - Techniques for tracking down "memory leaks"
