Tag: squid

varnish,squid,apache,nginx缓存文件比较

一，测试环境

1，硬件是奔腾双核，机子三年前买的。系统是archlinux

2，测试varnish和squid的时候，web服务用的apache

3，测试apache的时候，启动了5个进程，不过随着压力的增加，进程会增加的。

4，测试nginx的时候，启动了十个nginx进程，20个php-cgi进程

 

5，varnish，squid，nginx用的是反向代理的形势，也就是说访问图片的时候，要先透过缓存工具

二，测试

1，varnish

[root@BlackGhost bin]# /usr/local/bin/webbench -c 100 -t 20 http://127.0.0.1:8080/00/01/RwGowEtWvcQAAAAAAAAWHH0Rklg81.gif

100 clients, running 20 sec.

Speed=476508 pages/min, 47258114 bytes/sec.

访问了这么次，没有缓存只有一次，效率真的很高。

2，squid

从测试效果来说，squid挺让我失望的，在测试前，我心里是这样估计的，缓存最好的是varnish，其次是squid，然后nginx，最后是apache，现在呢，squid是最差的。后来我看了一下log文件，发现正常情况下，缓存和没有缓存的比率不是1：2，如果在高压力下，缓存和没有缓存的比率更小。

3，apache

4，nginx

从上面的测试结果我们可以发现，varnish > nginx > apache > squid，我想这个结果，根大家预期的结果有点出入，因为squid做老牌文件缓存工具怎么会这么差呢，squid的命中率低，我在网上查了一下，很多人都是这样的，这个可能根个人配置有关系，也许真正的高手，才能让squid发挥最大功力。
