<P>图片为测试结果统计图，通过Jmeter三个客户端分别发起100个线程，模拟不同的用户，也就是说理想状态应该同时有300个连接。但是统计web服务器的数据如下</P>

<P>请问是Jmeter不能模拟300个客户端不成功，还是服务器最大连接数只能达到60个并发访问</P>

jackei 你好，很感谢，你跟大伙分享的心得体会。我在工作遇到一个问题，想和你讨论一下：
前不久我用Jmeter 3 Agent, 1 Contrl 模拟300个并发进程进行测试，结果测试通过了。后来改用LoadRunner 模拟300个并发进程对同一server进行测试，服务器59sec时候挂掉了，查看日志，连接池超过150个，导致Java虚拟机挂了。by the way，我查看了网络连接的日志，jmeter模拟并发连接数，峰值大约是60个。http://bbs.51testing.com/thread-50486-1-1.html
所以我对Jmeter 分布测试的可靠性表示怀疑，不知你有没有做过相关的比较和验证。
