29、un Load Tests 虚拟虚拟IPIP设置设置设置IP欺骗的原因：当某个IP的访问过于频繁，或者访问量过大是，服务器会拒绝访问请求，这时候通过IP欺骗可以增加访问频率和访问量，以达到压力测试的效果。某些服务器配置了负载均衡，使用同一个IP不能测出系统的实际性能。LR中的IP欺骗通过调用不同的IP，可很大程度上的模拟实际使用中多IP访问和并测试服务器均衡处理的能力。注意：IP Spoofer 在连接Load Generators 之前启用。要使用IP 欺骗，各个Load Generator 机器必须使用固定的IP，不能使用动态IP。Any hard copy of this documen
