检查域名解析是否正确

域名需要全部做别名解析到s-xxxxx.abc188.com,特别是:智能多线/西部数码双线机房、

主机线路是否一致

检查一下您购买的是否是单线（中国电信）或者港台机房，如果是单线的主机跨网访问会比较慢，如果是港台

主机建议尽快备案后升级回国内机房

检查服务器资源使用是否正常

此处核查您主机的带宽，CPU，磁盘读写是否正常，如果有异常，请远程登录服务器检查一下原因

WEB站点性能优化实践（加载速度提升2s）

感谢大CC的投稿：进行优化前，关键是剖析当前的web性能，找到性能瓶颈，从而确定最需改进的地方;如果精力有限，首先将精力放在能明显提升性能的改进点上;《高性能网站建设指南》提出了一个性能黄金法则：只有10%-20%的最终用户响应时间花在了下载HTML文档上;其余的80%-90%的时间花在了下载页面中的所有组件上。由于本文将实施一个完整的优化流程，所以，我们还是从后台开始;案例说明：优化之前的网站规
