我正在使用siege加载测试我的api（nginx）.Api将POST请求从nginx转发到运行在8082的kafka rest服务器。
我正在使用四台ec2机器进行围攻。每当我看到围攻停止打了一段时间然后恢复。所以我强行用Ctrl + C打破围攻，我可以看到以下内容：
HTTP/1.1 200 0.01 secs: 121 bytes ==> POST http://my-ip/topics/jsontest

如果我不停止它，那么它会在一段时间后恢复击中，然后再次停止击打。当我强行阻止它时：

现在又一次能够达到21399-10699 = 10700大致相同的命中率。所以我想理解为什么它会在10699次点击后停止打击一段时间？ ec2-machine的限制？它只是降低了我的交易率，因为10699次点击后需要等待一段时间。我不想要的。这种情况发生在所有四台机器上。现在我的api在ec2实例上。但我可以从四台机器中分别打到10699次。但交易率非常低。
