Orinoco: young generation garbage collection
Summary
The article introduces Orinoco's parallel Scavenger for young-generation garbage collection in V8, detailing the evolution from Cheney’s semispace to newer parallel algorithms. It explains how generation-based GC works, contrasts three approaches, and presents performance improvements on real-world workloads, highlighting better utilization of multi-core CPUs and refinements for architectures like ARM big.LITTLE.
