Thanks!

I will look at this as soon as I am back home from my vacation and
then do a new benchmark run and update the benchmark page.

Regards,
Monty

PS: If anyone has any ideas of things that we have missed in our
    current benchmark pages, please email them to Anna so that she can
    add these to the next generation of the benchmark suite.

    Some things that I know we have missed in the single user
    benchmark are:
   - Sub select (all different forms of sub select, with a comparison
             to normal selects for those select that can be
         changed to normal selects)
   - Foreign keys (which should contain a comparison with multi-table-delete)
   - Transactions
   - Rollback

   With comparison I mean that there should be at least one test that
   makes it easy for the user to see which construct is better for
   this database.
