Ejabberd tsung 测试限制为 1005 个在线用户

Question

我需要测试我的 ejabberd 支持的最大在线用户数。我使用 tsung，但我遇到了问题，只有 1005 个来自 1 台客户端计算机的在线用户。

我已经运行 tsung -l tsung-logs -f chat-4k.xml start

chat-4k.xml 文件

  </session>
 </sessions>
</tsung>

一台客户端计算机上只有 1005 个在线用户。我已经在另一个客户端 VM 上运行了测试，它也提供了 1005 个在线用户。从 2 个客户端 VM a 仅生成 2010 个在线用户。

通日志有错误

如何通过一个客户端虚拟机增加连接在线用户？

看本教程的第1步，可能你的客户端受限，需要设置ulimit或者其他系统设置？ https://www.ejabberd.im/benchmark/index.html
