can this be confirmed as a bug?
I have run up a model for MOSS2007.
On the Model Editor, Global Topology page.
After I add a new site then add a site to site connection back to the central site (where the sharepoint farm resides).
I set the connection as Fractional T3 with 70% bandwidth available, then set the latency as 50ms.
I save the model, close SCCP.
Reopen the app then load the model.
The connection latencies on all the site to site links have reverted to 10ms.
(This is very frustrating!).
