This is the tool which I use for most of my tests. It is indeed a incredibly simple tool and I make no quips about that, going so far as describing it in the following manner: “A rudimentary ‘no bullshit’ benchmark tool primarily geared toward Debian-based distros.”
You can read the source here:

If you have any recommendations as to making the tool better, feel free to leave a comment or contact me by e-mail, or via GitHub. All contributions which makes this a better tool is certainly welcomed.
If you would like to try it out yourself, you can simply issue the following one-liner (requires elevated privileges):
curl -Lso- bad.goy.su/k0nsl-bench|bash
Have a great day!
