That's what "we" did several years ago : > http://people.freebsd.org/~kris/scaling/dfly.html i've seen that page some time ago but i don't really care of it. i just wasn't interested. Still - DOING such benchmark is good, as it can show general problems in used algorithms. But working on software to make it better in some kind of synthetic benchmark is common in commercial software world. ("We have more performance per buck than company X")
