 |
|
我的web服务器最近不知道是什么原因，反应非常之慢，现象如下：
a. 打开服务器上的网页要二十多秒；
b. ssh登录上去，发送命令和命令响应也非常慢，还很容易掉线；
c. sftp上传文件，哪怕是只有几K的文件，上传进度到100%就死在那里了，服务器上只建成了空文件。
可查看服务器参数，看起来负载似乎并不高。谁能帮我分析分析，服务器的系统参数正常么？
另外 ，如果是网络有问题，有什么好的方法可以查看和确认问题原因呢？
急，谢谢了。
下面是一些系统参数信息：
有若干链接的Send-Q比较大，而且总部释放。不知道是否正常？会不会是导致系统慢的原因？

网络问题，用ping啊，看响应，还有丢包率
用traceroute看经过的路由，以及各路由的延迟等等
