性能测试：fcgid方式

配置：

LoadModule fcgid_module modules/mod_fcgid.so

    AddHandler fcgid-script .fcgi .php
    #php.ini的存放目录
    FcgidInitialEnv PHPRC "e:/Servers/Apache-confs/"
    # 设置PHP_FCGI_MAX_REQUESTS大于或等于FcgidMaxRequestsPerProcess，防止php-cgi进程在处理完所有请求前退出
    FcgidInitialEnv PHP_FCGI_MAX_REQUESTS 500
    #php-cgi每个进程的最大请求数
    FcgidMaxRequestsPerProcess 500
    #php-cgi最大的进程数
    FcgidMaxProcesses 5
    #最大执行时间
    FcgidIOTimeout 120
    FcgidIdleTimeout 120
    #php-cgi的路径
    FcgidWrapper "e:/Servers/Php5.3/php-cgi.exe" .php
    AddType application/x-httpd-php .php

	Options Indexes FollowSymLinks ExecCGI
	Order allow,deny
	Allow from all
	AllowOverride All

测试结果：
