Dave: First, thanks for your input.
The site will be public and I do not know how many users will be accessing at this time. I realize there is no specific "user number", but I was trying to get a round number, if that's possible. >From a due deligence standpoint, how do you determine the server needs, if you can not determine the load each server can handle. Let's take the Flexstore example as a sample application. Can we determine using this scenario how many users? Roughly? Is it a general server issue or a Flex issue, regarding load performance?
