    What does this "benchmark" actually test?

    I apologize ahead of time if I posted to the wrong area...

    My test:

    time dd if=/dev/zero of=/dev/null bs=1024k count=1024

    I was dealing with a "sluggish" machine awhile back and thought this one up. I found that it was a pretty good way for me to test if my "tuning" attempts had improved overall performance.

    Now I find myself comparing machines... I can't stop!

    Anyway, would anyone care to enlighten me on which components of the box are getting tested?

    Thanks!
    Steve

    I only saw an increase in CPU activity when running that.
