英文:
Non HTTP response code: java.net.BindException Response message during load test in JMeter
问题
我想在JMeter中使用1500个虚拟用户进行负载测试，但我无法将负载增加到1000个虚拟用户以上。
我进行了一些研究和开发，并使用了两个负载生成器（LG1具有2个核心CPU，LG2具有4个核心CPU）。我观察到，使用LG1，我可以将负载增加到1000个虚拟用户，CPU使用率为100%（没有异常），但即使在600个虚拟用户之后，LG2开始出现“非HTTP响应代码：java.net.BindException”。
尽管LG2的配置高于LG1，但LG1的性能更好。
是否可以帮助回答以下两个问题：
1）为什么LG2会出现BindException错误，以及如何解决？
2）为什么具有4个核心的LG2无法比具有2个核心的LG1提高负载？
英文:
I want to do a load test with 1500VU in JMeter but I am NOT able to ramp up more than 1000VU.
I did some R&D and used two LGs (LG1 with 2 cores CPU and LG2 with 4 cores CPU) and I observed using LG1, I am able to ramp up upto 1000VU with 100% CPU usage(no exceptions), but LG2 starts throwing "Non HTTP response code: java.net.BindException" even after 600VU.
Even though the config is high for LG2 than LG1, LG1 is performing better.
Can anyone help to answer below two issues:
- Why LG2 is throwing BindException and what's the solution for that?
- Why LG2 with 4core is not able to ramp up more than LG1 with 2core?

我猜你正在尝试在Windows上运行JMeter。如果是这种情况，请考虑以下步骤：
如果由于缺少管理员权限而无法执行任何这些操作，则唯一的选择是获取更多的计算机并在分布模式下运行JMeter测试。
英文:
I guess you're trying to run JMeter on Windows. If this is the case consider the following steps:
- Increase ephemeral ports range
- Decrease the maximum time the connection spends in TIME_WAIT state
- Increase the maximum number of network connections if it's below 200
If you cannot do any of these due to lack of administrative permissions - the only option would be get more machines and run your JMeter test in distributed mode
