aware_support wroteMany people are using 64-bit with 7.0, so it's nothing new. 64-bit allows allocating memory beyond 1Gb barrier, nothing else. There is no correlation with the number of users.
The reason I raised this question, was because when MSFT moved ASP.Net (another framework that keeps session info per logged in user in memory during their session), MSFT was told by developers that ASP.Net in 64-bit can have more concurrent users when more memory was allocated and more sessions/users could be active.
So I was wondering if that same benefit would affect Aware server?
