Benchmarking CPU performance

We can use benchmarks such as Linpack (http://www.netlib.org/linpack/) and sysbench (https://github.com/nuodb/sysbench) to benchmark CPU performance. For this recipe, we'll use sysbench. We'll see how to run a benchmark on bare metal and inside the container. Similar steps can be performed in other environments, like we mentioned previously.

Getting ready

We will use the CentOS 7 container to run the benchmark inside the container. Ideally, we should have a system with CentOS 7 installed to get benchmark results on bare metal. For the container test, let's build the image from the Git repository that we referred to earlier:

    $ git clone https://github.com/redhat-performance/docker-performance.git
    $ cd docker-performance/Dockerfiles/
    $ docker image build -t c7perf --rm .
    $ docker image ls
    REPOSITORY      TAG       IMAGE ID      CREATED            SIZE
    c7perf          latest    59a10df39a82  1 minute ago      678.3 MB
