Nginx和Apache简单的并发压力测试

同样的环境，大小差不了几个字节的页面，

Nginx的worker_connections  1024;

Apache的MaxClients          150，worker模式；


照理说压Nginx如果用1024个并发压效果是最好的，同样压apache并发150的话效果也是最好的。


Nginx的测试结果：

[root@localhost nginx-0.7.19]# ab -t 60 -c 1024 http://192.168.1.101:8080/

Nginx5000个请求只花费了28秒就搞定。


Apache的测试结果：

[root@localhost nginx-0.7.19]# ab -t 60 -c 150 http://192.168.1.101/

Apache一分钟只搞定了4000个请求。


再试试，Nginx的并发150时候的速度：

[root@localhost nginx-0.7.19]# ab -t 60 -c 150 http://192.168.1.101:8080/

此次和上次Nginx1024个并发相比快了一秒钟，27秒搞定50000个请求


再试试，Apache的并发1024时候的速度：

我估计会被压死，先把帖子发出去，没压死再修改。。。

居然没有死机！ 结论：在我本机当前环境下，Nginx处理高并发小请求的速度要快于Apache。

 

高并发大请求的情况呢，有测试过吗？

大请求怎么衡量？

改天我写个Rails+Sqlite3的应用测测看，就是从Sqlite3里面查10条记录出来吧，不带索引。

web服务器应该用一个mongrel还是用mongrel集群啊？我只有一台机器，而且是虚拟机。

就这个多个服务器集群的问题。。就是很麻烦。。没有那么多电脑。。。公司有个台式机。。和自己的笔记本集群实验下。。。不知道如何。。哪里弄那么多电脑。。二手淘点。。

配置好的话就多弄出几个虚拟机。

拿Apache做压力测试都是没有理解Apache的精髓----稳定性第一, 性能第二. 2者使用完全不同的理念做的东西.

你理解我为什么那apache做压力测试么？

开始用nginx的时候大家都说它比apache快很多，所以纯跑一下http看谁处理短连接更快，没有关注apache是否比nginx更稳定。
现在用nginx在生产上的项目并不多，apache还是主流，就是因为apache的稳定大家都信任，而nginx还没经受过长时间的考验。

你说的没错，apache很稳定！
