Page 7: Memory
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... -

(i.e., 2.0 seconds), CPU utilization of the Microsoft Word portion of the test is consistently higher. The Microsoft Word and Microsoft Excel applications were started at the beginning of the test script and exited at the end of the script.

Page 18: Process Utilization
All processors use a single queue in which threads wait for processor cycles. This length does not include the threads that are currently executing. This is an instantaneous count, not an average over the time interval.

Page 24: Network Utilization
The % Network Utilization counter records the percent of network bandwidth in use for the local network segment. The following Performance Monitor chart characterizes the network traffic (i.e., % Network Utilization) while performing the 24 client session test for each of the LH 3. Figure 19 (24 Clients) Hewlett-Packard Company... - Page 25 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...

Page 26: Memory Utilization
The Committed Bytes counter records the amount of virtual memory that has been committed to either physical RAM or the pagefile. If the amount of committed bytes is larger than the amount of physical memory, it may indicate that more RAM is required.
