The BES server is running all services for BES except MDS, this includes MSDE2000. The mail server is separate as well as the sametime server. The version of Domino is consistent across all of it. NBES is currently 785 Meg, SQL 125 Meg, BMDS 120 Meg.
I've noticed later in the evening, changes via the Notes client are replicated much, much faster then during business hours. That's why I wasn't sure what I might be overlooking since according to RIM we meet the requirements for the amount of users we have.
I'm open to any suggestions.
