Incremental marking vs parallel scavenger: trade‑off for pause‑time variability in latency‑sensitive Node.js
The goal is to minimize GC‑induced pause‑time variability for latency‑sensitive Node.js workloads that allocate many short‑lived objects (e.g., Buffers in a tight loop). The constraint is choosing between V8’s incremental (Orinoco) marker, which spreads marking work to lower worst‑case pauses but adds write‑barrier overhead, and the parallel young‑generation
