These are questions that SAS Tech Support may be able to help you with so I suggest you open a track.   At the end of the day you will still have to do your own testing to prove performance is acceptable. When we implemented VA we set  a benchmark of 10 seconds maximum response on simple dashboards and 20 seconds maximum response on detailed reports. I suggest you do something similar as it is the response times for the users that count. If it is too slow they wont use it.   In our experience it is the data volumes, the number of VA-created columns and formulas, and report complexity that have the greatest influence on VA report performance. I don't imagine bandwidth will have much impact unless it is severely constrained. I'd also watch out for latency issues over long distance links as well. For example we have two data centres, one in the same city and one 800km distant. Switching from local to distant doubles the time for a SAS table to open (in Enterprise Guide) from around 10 seconds to 20 seconds.     ... View more
