多级缓存架构相当的给力

Mon.itor.us的检测结果表明,我的烂博客首页加载速度已经稳定在100ms左右的- –
目前博客逻辑架构是这样的:
前端:squid,跑在直连网通的xeex网络后,硬件是个小vps,128内存,xen架构,2G/150G,6刀一个月
后端:nginx反代httpd,同时nginx做部分静态文件服务器,硬件同样是个小vps,256内存,openvz架构,25G/250G,4刀一个月
数据库:mysqld,跑在上面那个256内存的vps上。
整个架构:squid>nginx>httpd>mysqld
用ab跑100个并发测试打开1000次首页,10多秒钟就搞定,服务器负载最多时候到了1- –
