    As with processor and memory utilization, network utilization will vary depending on user activity. As a general rule of thumb, Microsoft recommends 2 - 6Kbps per user (Microsoft Terminal Server Capacity Planning, White Paper). Network activity during our benchmark test averaged between 2 and 5Kbps per user. Hewlett-Packard Company...

    However, it is important to remember that, for purposes of our test, we used an isolated network with no additional traffic. In additional, our test script was not graphics intensive. As expected, as processor utilization increases network activity begins to level off. Hewlett-Packard Company...
