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.

  2. 서진우 말해보세요:

    ㅋㅋ네 예시가 적절하지 않았네요 실제 예시되라면 900가 맞습니다 공식이 잘못된것은 아니구요 지적 감사합니다

  3. 서진우 말해보세요:

    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.
