Node 22 gzip vs brotli — 1MB JSON 압축 시간·압축률 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 zlib 동기 API, 각 기본 품질(gzip level 6, brotli quality 11 — Node 기본값) 그대로, 반복 구조 JSON 1186KB 입력.

결과: gzip 20.1ms · 8.6:1 압축률 / brotli 3947.9ms · 12.9:1

해석: 기본 품질에서 brotli는 gzip 대비 압축률 50% 우위지만 시간이 196배다. 실시간 API 응답은 gzip(또는 brotli 품질 낮춤), CDN에 올리는 정적 자산은 brotli 최고 품질 프리컴프레션 — 경계값을 이 수치로 잡으면 된다. 반복 구조 JSON이라 압축률이 일반 텍스트보다 높게 나오고, brotli 기본 품질이 최고치(11)라 시간이 특히 큰 점 유의 — 품질을 낮추면 시간은 급감한다. 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.
