XPP 9.1 Compose and Abandon Times Over a WAN

We have workstations set up in an office and XPP server installed on a virtual server that is 5 miles away, connected via DS3 going through an Internet service provider.  The files are saved on a server that is local to the workstations.  If you have a similar remote XPP server, what are typical compose and abandon times you guys are getting for large files (870 pages, 16MB), medium files (150 pages, 1.2MB), and small files (50 pages, 500kb)?  We are looking to see if the times we are getting are typical for this type of setup.
