我有一个jmeter测试计划，该计划已运行40000个线程，启动时间为600秒。
我正在用命令行运行它。
./jmeter -n -t ../../HttpTestPlan.jmx
它在Windows 64位计算机上运行良好。它能够执行所有40000个线程而没有任何问题。
但是，当我在ec2中运行同一测试计划（具有root特权）时，它只能执行31208个线程，然后它将停止执行。
我应该怎么做才能确保它在linux ec2 box上运行所有线程？
谢谢

答案 0 :(得分：0)
您可能需要修改/proc/sys/kernel/threads-max设置
也请检查limits.conf，因为您可能需要增加打开手柄的最大数量
请注意，对于单个JMeter引擎而言，40k线程是相当大的数量，因此您可能需要考虑Distributed Testing，确保机器具有足够的空间来运行CPU，RAM，网络，磁盘IO等，就好像JMeter无法足够快地发送请求一样，即使您的应用程序不会超载并坚持使用JMeter Best Practices，吞吐量也会降低。
答案 1 :(得分：0)
很可能是由于JVM崩溃而生成了一个hs_err_pid.log文件。 搜索此类文件以查找JVM崩溃的根本原因。
假说中
请注意，40k线程需要一台强大的机器，并且很可能需要一个以上的机器才能克服： -卡的网络限制 - 中央处理器 -需要其他资源
您的机器（2个CPU，1Gb RAM）非常短。
