I have download the "mlc_v3.4.tgz" from the website, but I don't konw how to run the MLC to measure the latency and b/w. what are the commands should be excuted? and how can I find the binary to link?
You can run MLC as ./mlc without any arguments and it will produce several results. For more control, please refer to the readme file that is part of the download package
The executables are in the Linux and Windows subdirectories that are generated when you un-tar the archive. For the Linux binaries, no arguments are needed to the "mlc" binary to get useful results, but it needs to be run by the root user to get reliable latency measurements.
