Thanks for reminding me that 64bit translates to: recompile everything you need! I think this is exactly the choice of configuration we are going to make. Someone just reminded me that windows and linux come down to the same performance, but that the real overhead is on maintenance. It's true that linux implies less downtime, and you can always upgrade. On top of that, there's more granularity control on linux. Thanks for the info.
