Visual Test Scripts For each client session, a Visual Test 4.0 script was used to automatically generate keystrokes. Each client session ran the same script. The script used both Microsoft Word and Microsoft Excel to simulate heavy keystroke activity, pausing only 0.05 seconds between keystrokes - HP LH4r | HP Netserver & Microsoft Terminal Server 4.0 - Page 15
The following two screenshots were captured during a run of the Visual Test script. Figure 7 Hewlett-Packard Company 15 - HP LH4r | HP Netserver & Microsoft Terminal Server 4.0 - Page 16
was started as a background task on the server. Each Visual Test script was then started manually, as quickly as possible. Once all server. Test Results This section characterizes the behavior (i.e., elapsed time, processor utilization, network utilization and memory utilization) of HP NetServers - HP LH4r | HP Netserver & Microsoft Terminal Server 4.0 - Page 17
the elapsed time was computed and stored in a file on the server's disk. Elapsed time was calculated by subtracting the time the script client sessions for each of the tested server configurations.
