Resides) with a parameter stating that the system has 2048 MB of RAM, and the testing will be run as the Once installed, the simplest way to run Bonnie++ is to use the following command: bonnie++ -d /tmp -r 2048 -u ĭirectory (thus testing the performance of the drive on which /tmp Or install on Fedora, Red Hat, or CentOS with: sudo yum install bonnie++ Install on Debian and Ubuntu with: sudo apt-get install bonnie++ If the speed test is successful, the results, including the speed of each case and the software, CPU, and memory specifications, are uploaded automatically and. It doesn't come installed on most distros out of the box, but it should be available in the core repositories. Bonnie++īonnie++ is a free utility that's designed to benchmark file system and hard drive performance. Make sure you aren't doing anything else that might impact the readings, such as tranferring files. Whichever one you use, run the command multiple times to get multiple readings, and then average them together to get a more accurate sense of the performance. Timing cached reads: 3364 MB in 2.00 seconds = 1682.75 MB/sec` To test cached read performance: sudo hdparm -T /dev/sda2 Timing buffered disk reads: 180 MB in 3.00 seconds = 59.96 MB/sec` To test buffered read performance: sudo hdparm -t /dev/sda2 It's also highly configurable - with every test, you can specify different parameters such as how many test instances, how many CPU cores, how aggressive to test, how long to run, etc.Ĭovering all of the various commands and parameters is beyond the scope of this article, but this page on the Ubuntu wiki is an okay starting point. Once installed, stress-ng can test all kinds of stuff, including your CPU, RAM, I/O, network, virtual memory, and more. Install stress-ng on Fedora, Red Hat, and CentOS: sudo yum install stress-ng Install stress-ng on Debian and Ubuntu: sudo apt-get install stress-ng Certain components, especially CPUs and HDDs, will wear out faster when repeatedly stressed. Stress-ngĪs you might be able to glean from its name, stress-ng is a true stress test - it's extremely good for pushing your system to its limits, but because it can be so demanding, we don't recommend running it very often. After a moment, you’ll see the number 1 in brackets appear. It also comes in Live CD form called PTS Desktop Live, which lets you run it off of a CD, DVD, or USB drive so you can test any machine's hardware using a "clean" operating system on demand. To stress test a Mac with the yes command, open Terminal, type the following, and press Return to execute: yes > /dev/null &. Best of all, Phoronix is free and open source.
