Re: Other benchmark than OSDB

Hi,

I received the mail below, responding to some remarks I made here.  I
think it's good news.

  The above is of course wrong.  The license as you note below is
Artistic and you can use it how you wish.  But you can't use our
hardware to generate the numbers for marketing purposes.  Mark
was a little confused on that item.

  Let me explain the purpose of the tests.  They are to provide
an open source workload so that developers can share performance
information about this type of commercial workload in an open manner.
As you are familiar with TPC rules you can't share that sort of
working information in the open.  But there is no such restrictions
on these two workloads.  So if you wanted to share information
with the Linux Kernel folks on say, Asynic I/O performance
changes you can by posting to the wider lists.

   If you are a marketing guy I guess you could use the numbers
but you wouldn't have anything to compare to.  The real purpose
was to create the same type of stresses as a commercial database
benchmark so that the engineering issues could be worked in the
open.  Not to create the next marketing benchmark.
