[완료] apache 동시 접속에 관한 질문입니다.

아주 간단한 소스입니다.

<?php
// current time
echo date('h:i:s') . "<br />\n";
 
// sleep for 10 seconds
sleep(10);
 
// wake up !
echo date('h:i:s') . "\n";
 
?>

ab로 해본 결과를 보죠.

# ab -n 10 -c 10 http://192.168.0.10/10seconds.php

물론 requests를 동시에 100개 정도 보내면 프로세스가 생성되는 시간 때문에 10초 보다는 더 걸릴 수도 있습니다만.....
10개 정도라면 위의 결과처럼..... 거의 10초 대에 결과가 나와야 정상입니다.

저는 CentOS 5.2 x86_64 + Apache 2 (rpm) + PHP5 (rpm) 입니다.

아무 이상 없습니다.
