Thanks for your answer.

We received a questionair from SI for our sizing request. The questions
are very detailed and some only can be answered by an educated guess.
So we concluded that the advice can not be more reliable than our
educated guesses. Furthermore we also estimated that the advice of SI
would be oversized: they would never take a chance to advice too little
processing power. So our final conclusion was that we better make an
educated guess ourselves.

I got a similar advice from a collegue: 4 processors to start with
should be fine. He pointed out that internal memory though is essential
in performance. Any ideas how many GB's We should plugin into the
machine?
