Is there a benchmarker (a tool to measure computer performance) for Ubuntu (like SuperPI, 3DMark, or PCMark)?
There look to be a number of them listed in the Ubuntu Software Center (search "benchmark"), although the only one I've tried is System Profiler and Benchmark. It gives a lot of computer information and I've found it very useful, but you might want to try out a number of them.
The most complete benchmarking software is probably Phoronix test suite, which is available in the repositories and can be installed with:
It is up to you whether you choose yes or no, but there is nothing to be concerned with. You can still later upload results manually to openbenchmarking if you wish with the options in the program:
To list all the tests available (but not necessarily downloaded), run:
which gives tests such as these and many others:
To find information on any particular test, you can use:
Many of the tests are not installed by default and you can either download an individual test and run it with, for example:
To find the lists of thematic test suites, run
which returns such things as
As an example, you might want to run the entire suite of audio tests (instead of just one from those listed with the
For this test, some more of the related audio tests are downloaded and installed by the program and then the test is run.
There are a huge amount of tests to install and options to experiment with, but this test suite is definitely the one to use if you want to get some genuine benchmarks from your Ubuntu system that you can compare online at openbenchmarking and Phoronix.com.
It is not a quick, simple benchmarking application, but one that, with its multiple tests, will satisfy most areas of interest in regard to how things perform on Ubuntu.
However, benchmarking is a topic much debated and the forums are best suited for analysing which tests give the most useful results and how the tests should be setup; the one mentioned above,
Another option is sysbench. It is a command line tool with built in tests for CPU, memory, file, threading and database. There is an article about it here. Install is a single package, and running tests is quick.
Likely the quality of results is lower than more sophisticated tests, but I found it useful for a quick sanity check when evaluating potential VPS hosting.
Based on the popular answer by user76204, I did try Phoronix test suite. As the author says, it is not quick or simple. There are 100s of tests available and it's not obvious which to use. Some require 100s of MB of downloads, some take an hour or more to run, some may not run on your server. On Ubuntu, I hit a bug described here.
