Dave Täht describes
the Flent network-testing tool and its use in great detail.

With flent – in the 110 tests in it – in a matter of minutes you
can replicate any network stress test “out there” and compare
networking results across an extraordinary number of variables,
over time, across many tests. Before Toke Høiland-Jørgensen
developed flent, it would take days to set up a single test and
single plot. Now you can be deluged in data, graph it quickly, and
can investigate network behaviors in minutes that take other
support staff, engineers and SREs months, plot accurately, over
each change you make, with comparable results in a standardized
file format, and a zillion useful plot types.
