I will be testing the performance of each Raspberry Pi version in my cluster. This is to determine what each one is best suited to running. To do this I need a similar set of tests to run for each and compare them.<\/p>\n

Ideally the tests will also be runnable on other embedded Linux devices so that I may further collect comparison figures.<\/p>\n

For now I am going to focus on performing my testing on a Raspberry Pi. Here I will detail what my testing Raspberry Pi SD card will do.<\/p>\n

Setting up the OS<\/span><\/h2>\n

A test OS has been set up to use for all the Raspberry Pi performance testing. For this I have chosen Raspbian Jessie Lite. Part of the reasoning is that I want to test the Raspberry Pi running a base set of programs so I can measure the true performance.<\/p>\n

Once the OS was installed I ran a number of maintenance jobs and tasks to set up the SD card for performance testing. I performed the following actions.<\/p>\n

    \n
  1. Burned Raspbian Jessie Lite to a SD card<\/li>\n
  2. Added a file with the name\u00a0SSH<\/code>\u00a0to the boot directory, to allow SSH access by default LINK ME<\/li>\n
  3. SSH’ed into the Raspberry Pi and changed the hostname to “bunker-speedtest”<\/li>\n
  4. Changed the password of the default pi user (make sure you always do this)<\/li>\n
  5. Updated raspbi-config to the latest version<\/li>\n
  6. Updated the Raspberry Pi with apt-get update<\/code> and apt-get upgrade<\/code><\/li>\n<\/ol>\n

    Once this has been done I had an image that I would be able to then prepare my speed test programs for.<\/p>\n

    Testing with\u00a0sysbench<\/h2>\n

    For now I am going to be using a program called sysbench to run a number of benchmarks on my Raspberry Pi’s. Some of the main functions that this can test are CPU, RAM, File IO and database performance.<\/p>\n

    One of the main reasons to use this is that pre-compiled binaries are available for many distributions. This means that when I expand my metrics to other embedded linux systems I will be able to run the metrics on these too.<\/p>\n

    Sysbench can be installed on Raspbian using the following command.<\/p>\n

    sudo apt-get install sysbench<\/pre>\n
    Now that I have a SD card set up to run performance testing I shall look towards collecting data on this performance.<\/p>\n
