    Hi Steve,

      I will upload them in a minute and post the link. I was thinking I would also
    stream line my PHP files I use for running the benchmark(s) and include those.
    This way other people on the list can run the same test. It's not scientific
    perhaps, but at the end of the day, I want to know what my database server is
    able to achieve in the real world when it comes to stuff like inserts, updates,
    searches.

      I'll send another e-mail in a minute. Gotta finish lunch :)

    Ray
