Avg. User Logon Scripts Execution Time

Summary

Monitors the average user logon scripts execution time (in seconds) for a delivery group. This logon phase covers the time taken for the logon scripts to be executed.

Configuration

Causes

Logon scripts can have a large impact on start time. Some of the most common ways that logon scripts increase logon times are:

• Slow or resource-intensive startup scripts (for example, those that move large numbers of files).

• Inefficient loops in scripts.

• Nested calls to different scripts.

Also, please see the Delivery Group - Logons per Week (Plan & Manage) report to view how the average logon phase time changed for the past weeks.

Some scripts may complete a lot of actions, including calls to other scripts, long loops, mapping network drives, and others.

Optimize and merge logon scripts where possible. Windows Server 2008 introduced Group Policy Preferences, which when used can reduce, or in some cases eliminate, the need for logon scripts. When not using Group Policy Preferences, assign logon scripts to users via GPOs, rather than the AD User Account property setting.
