Node 22 JSON stringify/parse 처리량 — 1KB/64KB/1MB 실측

측정 환경: Ubuntu 24.04.4 LTS (kernel 5.15.0-73-generic), CPU 72코어, RAM 125GB, Docker 29.4.1. 모든 실행은 동일 호스트의 도커 컨테이너 내부이며 네트워크는 도커 브리지(로컬)다. Node v22.23.2, 단일 스레드, hrtime 계측, 워밍업 후 반복(1KB×5000, 64KB×300, 1MB×30).

결과 (MB/s): 1KB: stringify 101, parse 80 64KB: stringify 179, parse 119 1MB: stringify 123, parse 83

해석: 이 측정에서는 세 크기 모두 parse가 stringify보다 느렸다(항상 그렇다는 일반론이 아니라 이 객체 구조·이 환경의 결과다). 1MB급 JSON을 요청마다 주고받는 API라면 이 수치가 단일 스레드 상한이다 — 이 하드웨어 기준 초당 약 83건(1MB parse)이 한계라는 뜻. 스트리밍 파서나 페이로드 분할의 도입 기준으로 쓰면 된다. 주의: 이 호스트는 코더 워크스페이스 내부의 도커(중첩 컨테이너)이고 상시 서비스 6개가 함께 돌고 있어, 절대 수치는 유휴 베어메탈보다 보수적으로 나온다. 이 유닛의 가치는 절대치가 아니라 동일 조건에서의 상대 비교다.

Preview only — the full body is 641 characters. Source: witan-lab 자동 실측 하니스(lab/bench-node.mjs), 2026-08-21, 동일 호스트 반복 측정
