Varnish是一款高性能的开源HTTP加速器,挪威最大的在线报纸 Verdens Gang (vg.no) 使用3台Varnish代替了原来的12台squid,性能比以前更好。
Varnish的作者Poul-Henning Kamp是FreeBSD的内核开发者之一,他认为现在的计算机比起1975年已经复杂许多。在1975年时,储存媒介只有两种:内存与硬盘。但现在计算机系统的内存除了主存外,还包括了cpu内的L1、L2,甚至有L3快取。硬盘上也有自己的快取装置,因此squid cache自行处理物件替换的架构不可能得知这些情况而做到最佳化,但操作系统可以得知这些情况,所以这部份的工作应该交给操作系统处理,这就是Varnish cache设计架构。
Varnish可以在FreeBSD 6.0和Linux 2.6内核上运行。
1、编译安装varnish HTTP加速器:
2、简单启动varnish守护进程,用本机80端口去反向代理加速127.0.0.1:81上的Apache服务器:

另有一份PDF文档,说明Varnish原理的:http://ishare.iask.sina.com.cn/cgi-bin/fileid.cgi?fileid=2163384
我测试了一下,在同等配置环境下,Varnish的性能确实要超过Squid,稳定性也不错,值得继续去深入研究。
