![]() ![]() I figured there was some type of hardware failure going on, so I tried to consume all the RAM in the system and then read it back in to see if the hardware failure was related to the RAM. astromechza / cpueater.java Last active 2 months ago Star 7 Fork 1 Code Revisions 2 Stars 7 Forks 1 Embed Download ZIP Simple java program for running multi-threaded cpu stress test. Like anyone who doesnt know it yet, the Apache JMeter application is open source software, a 100 pure Java application designed to test functional behavior. GitHub Instantly share code, notes, and snippets. I wrote a program similar to this when I started getting the Windows blue screen of death several times. Simple java program for running multi-threaded cpu stress test. As I write about in this How to control Java heap size (memory) allocation (xmx, xms) post, you can also specify the Xmx parameter in gigabytes, such as this setting for one gigabyte: Troubleshooting High CPU and Memory Leaks in Java Processes by Amar Gurung Zaloni Engineering Apr, 2021 Medium Zaloni Engineering 500 Apologies, but something went wrong on our end. The example shown above will try to consume up to 1,024 MB RAM (1 GB). It’s also important to run this Java memory eating program with the -Xmx option to make sure your JVM gets all the memory you want it to have: ex: (30-50), (51-70) and >90 So I need a cpu stresser that can simulate specific cpu percentage per core. ![]() ![]() Its purpose is to consume all of the memory (RAM) on a PC by allocating 1 MB byte arrays until it runs out of RAM: Test monitoring program that set alarms and trigger different alarms at different cpu percentages. One of the first indicators of a runtime performance problem is a high Java CPU usage report from a JVM profiler or Java monitoring tool. 2.- Get a baseline for the system under normal expected load. As a general guideline, when doing performance you should always: 1.- Get a baseline for the system on an idle state. Here’s the source code for a Java “memory eating” program I wrote. Finally, Performance test individually any critical components you have identified or would like to keep tracked on your app. ![]()
