The Mad Cousin
summary
Nexus claims to run server JavaScript across cores by replacing V8’s single event loop with JavaScriptCore and a thread pool that schedules callbacks on multiple threads, using a lock‑based atomic model and a lock‑free priority queue. It implements promise-based event emitter semantics, ArrayBuffer stream filters, file push/pull devices, and per‑promise parallel handlers. Examples show scaling to cores and logical CPUs (four cores × two logical = eight threads), a concurrency flag (concurrency=1), and measured higher throughput and lower RAM compared to multiple Node processes.
