Stress-ng -vm 32 -vm-bytes 64M -vm-stride 1K -vm-populate -page-in -metrics-brief -times -timeout 60sĬheck Stress-NG documentation for more details. These can be specified using the -vm-method option Stress-ng -cpu 4 -io 2 -timeout 60s -metrics Stress-ng -cpu 4 -io 2 -vm 1 -vm-bytes 256M -timeout 60s These can be specified using the -cpu-method option Open the terminal and run the following command One can specify the number of processes to invoke per type of stress test specifying a negative or zero value will select the number of online processors as defined by sysconf(_SC_NPROCESSORS_ONLN). OCCT, which stresses your PC as much as these other programs, also provides a handy monitoring interface to keep track of temps, clocks speeds, and CPU usage over time. With the apropriate privilege, stress-ng can allow the ionice class and ionice levels to be adjusted, again, this should be used with care. However, running a 3-4 hours test will ensure that your CPU is not unstable and can take on heavy loads throughout the day. Running stress-ng with root privileges will adjust out of memory settings on Linux systems to make the stressors unkillable in low memory situations, so use this judiciously. However, it has never been intended to be used as a precise benchmark test suite, so do NOT use it in this manner. Stress-ng can also measure test throughput rates this can be useful to observe performance changes across different operating system releases or types of hardware. Use stress-ng with caution as some of the tests can make a system run hot on poorly designed hardware and also can cause excessive system thrashing which may be difficult to stop. Stress-ng was originally intended to make a machine work hard and trip hardware issues such as thermal overruns as well as operating system bugs that only occur when a system is being thrashed hard. Over 50 CPU specific stress tests that exercise floating point, integer, bit manipulation and control flow It was designed to exercise various physical subsystems of a computer as well as the various operating system kernel interfaces. Stress-ng will stress test a computer system in various selectable ways.
