EPM, Project Server 2003, Project Server 2007, MOSS 2007, Portfolio Server2007
I recently did a study to evaluate the bandwidth requirements for an outsourced EPM 2007 deployment.
The Tool Fiddler was used to measure the http traffic (http://www.fiddlertool.com).
The bandwidth is hard to estimate with EPM because the amount of data transferred depends of the customization done with the default product:
The measures were done with an administrator account, so that it gives a maximum value.
Typical usage and measure:
Project Web Access operations:
Reporting (using Reporting Services)
The users are distributed around the world
Results This is just an example of measure, and it cannot be generalized. It depends on the size of projects and the reports.
