가상머신에 리눅스를 깔아놓은 상태입니다..
예를 들어 Nginx와 openlitespeed의 성능을 비교하고싶다면,
엔진엑스를 yum install로 설치해서 80포트와 연결해서(웹브라우저에 'localhost'라고 치면 Welcome to Nginx!가 나오게)
ab -c 1000 -n 1000 -t 10 localhost/
(openlitespeed할떄는 service nginx stop 해준 후 yum설치 등 마찬가지 방식)
이렇게 해주면 되는건가요?..
생각보다 너무 간단한거 같아서용
우선 시험삼아
ab -c 50 -n 50 -t 3 localhost/
이렇게 몇번 돌려봣는데 결과가 많이 달라서 좀 의심스럽네요
제가 뭘 잘못하고 있는건가요?

보시다시피 이렇게 차이가 많이 납니다(특히 Connection TIme)
