성능 개선률 산정 공식
(튜닝 전 응답 속도 – 튜닝 후 응답 속도) x 100 / 튜닝 후 응답 속도 = 개선율(%)
예) 1초에서 0.1초로 개선되었다면 개선율은 900%가 된다.

죄송한데요. 공식대로면 900%가 됩니다. 분모가 튜닝 전 응답속도여야, 의도하신 답이 되지 않을까 싶으네요.
ㅋㅋ네 예시가 적절하지 않았네요 실제 예시되라면 900가 맞습니다 공식이 잘못된것은 아니구요 지적 감사합니다
간혹 개선률과 절감률을 동일시 하는 경우가 있는데, 다른 표현임.
어찌보면 절감효과 자체가 개선이라 볼수 있지만, 이는 변경 사항이 전, 후 중 어느것을 기준으로 한 표현으로 개선률은 변경후를 절감률은 변경전의 값을 기준으로 함.
절감률=(튜닝 전 응답속도 – 튜닝 후 응답속도) X 100/튜닝 전 응답속도
위 예제라면 응답시간이 90% 절감되었다고 볼수 있습니다.
