Re: When do you need a 3-tier architecture?

I'm not sure +1 tiers == greater performance. For starters you have to negate the transactional costs of communication between the two which includes network I/O. Testing and debugging can also be a lot harder. When your system blows, you need good error logging to know exactly where it went wrong. And to do that you have to pass errors between tiers.
