Explore the inner workings of the Shenandoah garbage collector in this 26-minute conference talk from GOTOpia Europe 2020. Delve into the promise of sub-10ms pause times and learn how work-stealing algorithms optimize garbage collection performance. Discover the challenges and unexpected outcomes in implementing work-stealing, understand the impact of worker thread count, and examine the evolution of work-stealing in JDK 11. Investigate the role of biases in garbage collection and consider potential future improvements to further enhance Shenandoah's efficiency.
