　　最近在做性能测试时，在使用netstat命令查看本地网络连接状态时发现有大量的连接处于time_wait状态。　　于是认为是我们的dbcp的配置文件写的有问题，开始查应如何配置dbcp。但是改了几个参数后，发现还是出现大量的time_wait。　　于是又开始查看官方的配置说明，还是我们老大认真犀利，发现了这段：　　If maxIdle is set too low on heavily loaded systems it is possible you will see connections being closed and almost immediately new connections being opened. This is a result of the active threads momentarily closing connections faster than they are opening them, causing the number of idle conn

0:30:44 how to determine the number of routers from the local machine to another machine: You can use the TTL command in the ping command to estimate that the default TTL value is 64,128. Each time a vro passes through a route minus 1, for example, PingWww.baidu.com The approximate route is: 64-52 = 12 Use the tracert command to obtain the router that passes through. The tracert command is as fol
