This is the blog of Ronald Bartels that wanders on and off the subject of problem management (that is how it started), but it is best described by Ray who says this is Daddy's thoughts! Like the best music is from the Eighties and a wee dram helps in solving most inconveniences.
iperf2 - A tool for measuring TCP and UDP network performance
A network traffic tool for measuring TCP and UDP performance. The goals
include maintaining an active iperf 2 code base (code originated from
iperf 2.0.5), preserving interoperability with iperf 2.0.5 clients and
servers, preserving the output for scripts (new enhanced output requires
-e), adopt known 2.0.x bug fixes, maintain broad platform support, as
well as add some essential feature enhancements mostly driven by WiFi
testing needs. Also added python code to centralize test control.
