I thanks you for your participation but not for the way you do it 
because if you had read my second mail on this topic you wouldn't have 
to ask your crystal sphere to wonder what is my configuration !!

My questions are septics because we have performance problem with our 
cyrus configuration. We must do something and I'm here trying to compare 
  what will be the best solution for us. I can do some mistakes because 
it will be temporary but if I find the good server with one try It will 
be better for our next architecture.

Thanks again for your help.
