![]() ![]() Combining tests can give a more realistic workflow of a busy server, mimicing usage of CPU, RAM and storage as if it were in regular use. This combines a selection of all the above tests for 900 seconds. Stress -hdd 2 -io 4 -vm 6 -cpu 8 -timeout 900s This will start a 4-thread test running write()/unlink(), which will write data to the system's storage and then delete it, for 900 seconds. This will start a 4-thread test running sync(), to stress the system's storage read and read buffers, for 900 seconds. This will start a 4-thread stress test, running malloc() and free() functions continually, for a period of 900 seconds. Please edit as you see fit for your workload and requirements: ![]() Here are a small selection of useful tests. I used Linux exclusively for 3 or 4 months at a certain point on my laptop, and it was probably the best months I ever had on my laptop. But a distro called Ubuntu is reducing the difficulty of simple PC users using Linux. Though, if your system has HyperThreading (HT) or Simultaneous MultiThreading (SMT) technologies, you might want to use 8 threads so that your threaded cores are utilised too. Common Questions and Answers about Cpu stress test for linux. If your system is a quad core, then this should sufficiently tax all cores. If all goes well, a 30 second torture test should be executed on the CPU, using 4 seperate threads. To start, let's run a short 4-thread CPU test: stress -cpu 4 -timeout 30 From there, open a terminal window and type the following to start the GpuTest GUI: python gputestgui.py Choose your stress-testing method in the GUI menu that appears, then click the Run stress test button to begin the stress testing. Now that it's installed, we need to tell it to do something. To install it on Linux, download the most recent release of GpuTest and unzip the file. Whereas RHEL/CentOS/Fedora, we need to first enable the EPEL repository (which is generally safe, but proceed with moderate caution as this can change package versions!)then install stress: yum install epel-release On Debian/Ubuntu you should use: apt install stress-ng This can be done with the nifty stress tool that is available in most Linux distributions.įirst, let's install the stress-ng package. When a dedicated server is crashing or its hardware otherwise misbehaving under load, it is helpful to induce a 'fake load' onto the system to help diagnose the problem.
