Changes since v1.0.1 include:

  • A complete overhaul of the plotting code so that it now uses the exact
    data points captured from the test tools wherever possible, instead of
    interpolating values to align data points on the time axis. This
    should improve the accuracy of plots, especially for integer-value
    data series such as packet drops.

  • The GUI has gained a new widget that makes it possible to control all
    plot-related settings. Previously, only a few of the settings for
    generating plots that are available on the command line could be set
    from within the GUI; now, the full set of command line settings can be
    manipulated in the GUI settings pane as well.

  • Another rewrite of the plot layout algorithm which should result in
    fewer issues with plot elements such as titles being drawn on top of
    the plot.

  • More keyboard shortcuts in the GUI: Ctrl+Up/Down will move between
    different plots, and x/X and y/Y will zoom the axes in/out.

  • By default, batch run order is now randomised to prevent periodic
    errors biasing results in long tests. This can be turned off with
    the --batch-no-shuffle option.

  • Netperf is now instructed to prefill its buffers with random data,
    instead of the data packets consisting repeated 7-byte strings
    ('netperf'). This ensures that data flows are not trivially
    compressible, which should improve test accuracy on encapsulated
    connections that enable compression.

  • Added support for setting TCP congestion control and diffserv markings
    as test parameters for some tests.

  • Added support for capturing socket statistics for TCP flows and store
    them as an auxiliary data set. This makes it possible to capture
    window size and RTT estimates from the kernel TCP state machine (Linux
    only). Thanks to Matthias Tafelmeier for the initial implementation of
    this feature.

  • Added support for watchdog timers to make sure runners don't go over
    time. This is applied to the fping runner thus far.

  • More metadata is captured from test runs; in particular, Netperf
    TCP_INFO variables, the congestion control used for each flow and
    socket buffer sizes are captured for every flow and stored in the
    metadata object.

  • Numerous bug fixes throughout.
