关于web服务器访问速度慢的一些简单解决方法

首先要考虑下 访问的用户: 

[root@app opt2]# netstat -ant | grep $ip:80
tcp        0      0 :::80                       :::*                        LISTEN

tcp        0      0 ::ffff:192.168.100.101:80   ::ffff:66.249.67.92:47812   TIME_WAIT   
tcp        0      0 ::ffff:192.168.100.101:80   ::ffff:221.204.172.135:3907 FIN_WAIT2   
tcp        0      0 ::ffff:192.168.100.101:80   ::ffff:221.204.172.135:3911 FIN_WAIT2

当然我们也可以对ip进行 过来和统计

[root@app opt2]# netstat -ant | grep $ip:80 | grep EST | wc -l

当然关于更多的 netstat命令的状态解析请移步到: 这里

这里如果你的网站访问过慢还有一个可能就是 你的apache工作模式的调试 mpm的设置。如果设置不当，可能会导致资源利用不合理从而使网站访问过慢。这个问题网上资料比较多我这里就只指个方向。apache工作模式  即可获得更多信息
