====== Benchmark Linux VM ======

Topic comes up from now an then to inspect the performance of a certain VM.

An easy and standardised way is the Phoronix Test Suite: https://www.phoronix-test-suite.com/


===== Requirements Debian =====

to download and build benchmarks, the following packages are needed:


  * Unordered List Item libpopt-dev
  * build-essential
  * autoconf
  * mesa-utils
  * vulkan-utils
  * unzip
  * apt-file
  * php-cli
  * php-xml

install with:

<code>
$ apt install libpopt-dev build-essential autoconf mesa-utils vulkan-utils unzip apt-file php-cli php-xml 
</code>

===== Download binaries =====

<code>
wget https://phoronix-test-suite.com/releases/phoronix-test-suite-10.2.2.tar.gz && \
tar xvf phoronix-test-suite-10.2.2.tar.gz && \
cd phoronix-test-suite
</code>

===== Run Benchmarks =====

Run a test with the following syntax:

<code>
./phoronix-test-suite benchmark [name]
</code>

=== Tests to use ===

There are 100s of tests. Two easy to run and small tests are:


  * c-ray (for cpu performance)
  * dbench (for io performance)

You might choose different tests based on your needs.

After the test, a summary of the results is displayed. If the test-file was saved, it can be later retrieved with:

<code>
./phoronix-test-suite show-results [result-name]
</code>
Phoronix test suite ist linked to Openbenchmarking.org. The site provides a vast number of results to compare to.
