测试环境:
vr.org 的 VPS
CPU:2核共享
内存:512M独立
OS:Ubuntu 12.04 LTS x64
uname -a u1@www:~$ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=12.04 DISTRIB_CODENAME=precise DISTRIB_DESCRIPTION="Ubuntu 12.04 LTS" u1@www:~$ uname -a Linux www.shaixuan.org 3.4.0-cloud #1 SMP Thu May 24 04:54:53 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux u1@www:~$ top top - 23:57:39 up 1:38, 2 users, load average: 0.04, 0.03, 0.16 Tasks: 55 total, 1 running, 54 sleeping, 0 stopped, 0 zombie Cpu(s): 0.7%us, 0.4%sy, 0.0%ni, 97.6%id, 0.1%wa, 0.0%hi, 0.1%si, 1.1%st Mem: 506764k total, 125264k used, 381500k free, 7736k buffers Swap: 499708k total, 0k used, 499708k free, 70096k cached软件版本:Apache httpd 2.4.3、nginx 1.2.3、lighttpd 1.4.31、php 5.4.6
结论:
静态服务器:
并发:nginx(17000)> lighttpd(14000)> apache(5000)
注意:lighttpd开启gzip压缩时,无法禁用etag……不建议使用。参考:《高性能网站建设指南》
动态服务器:
大约并发:nginx + php-fpm(1500)> lighttpd + spawn-fcgi(1000)>apache + php module(400)
注意:web server与fastcgi在同一个机器时,建议使用unix domain socket,比tcp socket效果好一点点。
虽然apache httpd 2.4 像 nginx一样使用了epoll,但是性能还是比nginx低很多。
服务器OS一定要使用Linux 2.6内核及更高,因为才能支持epoll。
建议服务器使用Ubuntu server LTS x64,因为工程师PC使用Ubuntu x64较多(Ubuntu的显卡驱动安装方便),这样编译部署都一致。
Ubuntu、CentOS等各个Linux发行版对服务器来说没有区别,内核都一样,挑一个顺手的即可。

测试过程:
Apache httpd 2.4.3
编译参数:

To increase, please see the ServerLimit directive.
nginx 1.2.3:
编译参数:
View Code ./configure --prefix=/usr/local/nginx --with-pcre=/usr/local/pcre
lighttpd 1.4.31:
默认并发1024,server.max-fds最大可修改为65535,server.max-connections最大可修改为32767:
193 ## 194 ## As lighttpd is a single-threaded server, its main resource limit is 195 ## the number of file descriptors, which is set to 1024 by default (on 196 ## most systems). 197 ## 198 ## If you are running a high-traffic site you might want to increase this 199 ## limit by setting server.max-fds. 200 ## 201 ## Changing this setting requires root permissions on startup. see 202 ## server.username/server.groupname. 203 ## 204 ## By default lighttpd would not change the operation system default. 205 ## But setting it to 2048 is a better default for busy servers. 206 ## 207 server.max-fds = 2048 218 219 ## 220 ## Fine tuning for the request handling 221 ## 222 ## max-connections == max-fds/2 (maybe /3) 223 ## means the other file handles are used for fastcgi/files 224 ## 225 server.max-connections = 1024
1、静态服务器测试
即apache、nginx、lighttpd性能对比。
服务器相同配置 :
开启gzip、关闭etag
测试程序和web server在同一台服务器上,测试命令:
ab -c 1000 -n 50000 http://localhost/index.html siege -c 1000 -r 20 http://localhost/index.html
apache:html文件13k,gzip压缩为4.9k

2、动态服务器测试
即apache + php module、nginx + php-fpm、nginx + php-cgi、lighttpd + spawn-fcgi对比。
测试命令:
siege -c 1200 -r 20 http://localhost/phpinfo.php /usr/local/apache2/bin/ab -c 100 -t 50 http://localhost/phpinfo.php
php版本 5.4.6,测试代码phpinfo();
apache + php module:php文件63.57k,gzip压缩为11.21k
测试结果:

nginx + php-fpm(多个php-fpm子进程):php文件57.41k,gzip压缩为10.84k
phpinfo显示Server API:FPM/FastCGI
fastcgi的socket方式:tcp socket
php编译参数:
php-fpm ./configure --prefix=/usr/local/php-fpm --enable-fpm --with-fpm-user=www-data --with-fpm-group=www-data --with-curl --with-mcrypt --enable-mbstring --enable-pdo --with-pdo-mysql=mysqlnd --with-mysqli=mysqlnd --enable-zip测试结果:

nginx + php-fpm(多个php-fpm子进程):php文件54.57k,gzip压缩为9.16k

测试结果:

nginx + 一个php-cgi:php文件64.65k,gzip压缩为11.89k
sudo /usr/local/php-fpm/bin/php-cgi -b 9000 -q
php-cgi可以常驻(long-live)监听一个端口,所以是fastcgi,但是由于没有进程管理器,只能启动一个进程,并发承受力低。
phpinfo显示Server API:FPM/FastCGI
测试结果:
并发100时,经过5秒,php-cgi崩溃退出。
lighttpd + lighttpd自带的spawn-fcgi进程管理器(多个php-cgi子进程):php文件58.68k,gzip压缩为9.83k
phpinfo显示Server API:CGI/FastCGI
fastcgi的socket方式:unix domain socket
lighttpd的fastcgi.conf配置:
fastcgi.server 22 fastcgi.server = ( ".php" => 23 ( "php-local" => 24 ( 25 "socket" => socket_dir + "/php-fastcgi-1.socket", 26 "bin-path" => "/usr/local/php-fpm/bin/php-cgi", 27 "max-procs" => 2, 28 "broken-scriptfilename" => "enable", 29 "bin-environment" => ( 30 "PHP_FCGI_CHILDREN" => "16", 31 "PHP_FCGI_MAX_REQUESTS" => "500", 32 ), 33 ) 34 ),测试结果:
