为什么在本地测试ajax反应很慢
在本地测试ajax接收分页数据 要反应1s左右（以上） 但是放到服务器上就100ms到 900多ms之间 有什么好的办法解决ajax获取速度慢吗 已经把分页数据换成json了 没多大改善
数据大小显示是在2.9kb 耗时1.03s 处理逻辑就是简单查询了一下mysql的10条信息 字段也就3个
又测试了一下 返回一个很小的 392b的数据 还是返回在1s左右 应该是我本地数据库查询慢的问题了吗？
用的是jquery加ajax

这个问题很可能是你的本地是支持IPv6，并且你本地的Mysql支持反向解析惹的祸。
问题的解决办法有三种：
修改本地连接数据库
localhost改为127.0.0.1，这是最简单的办法。注册表禁用IPv6
MySql禁用反向解析。

需要先看看慢在了哪里。从数据上看似乎还是后台处理逻辑耗时长，这个就要看实现的逻辑怎么调优了。另外建议用chrome的开发者工具看看request各段的响应时间，再诊断一下是不是和网络有关。
@lovnie 问问题是需要技巧的，一个简单的办法是自问自答。
问：ajax请求本地慢，服务器快，是哪里导致的？
答：本地不太可能是网络问题，那就是后台接口慢咯！（那就debug调试看看接口响应时间啦）
问：接口哪里慢？（假设之前的分析是对的）
答：加上日志，分析耗时代码在哪里
然后这个问题就变成了XXX代码运行的为什么这么慢，再搜索一把，自己分析一下，解决不了再来提问，这样问题显得高级多了
