如何在 Windows 中增加 JVM 运行时内存 [英] How to increase JVM Runtime Memory in windows
问题描述
我正在尝试通过命令行运行脚本，因为我正在使用下面的命令
I am trying to run the script through command line for that I am using below command
C:apache-jmeter-4.0apache-jmeter-4.0in>jmeter -f -n -t C:apache-jmeter-4.0apache-jmeter-4.0inexamplesPost_call_24_FirstStep_10.jmx -l C:apache-jmeter-4.0apache-jmeter-4.0inexamplesCSVDATATest.csv
但它给出了以下错误
Java HotSpot(TM) Client VM warning: INFO: os::commit_memory(0x05400000, 1073741824, 0) failed; error='The paging file is too small for this operation to complet e' (DOS error/errno=1455)

推荐答案
根据你得到的错误:
页面文件太小，无法完成此操作
The paging file is too small for this operation to complete
您需要增加虚拟内存(交换文件)的大小，请参阅如何更改 Windows 8 或 Windows Server 上的虚拟内存 (pagefile.sys) 的大小2012 指南了解更多详情.
You need to increase size of virtual memory (swap file), see How to Change The Size of Virtual Memory (pagefile.sys) on Windows 8 or Windows Server 2012 guide for more details.
但是请注意，使用交换会对 JMeter 的性能产生显着的负面影响，因此如果可用物理 RAM 不足，最好考虑 分布式测试 - 即在多台主机上运行 JMeter slaves，因为你很可能无法从一台机器创建所需的负载.
However be aware that using swap will dramatically negatively impact JMeter's performance so if you're running out of available physical RAM it is better to consider Distributed Testing - i.e. run JMeter slaves on multiple hosts as most likely you won't be able to create the required load from a single machine.
