What can I do to improve my startup performance?

By default, in rich client tree views a checked-out symbol displays to the right of checked out Teamcenter objects. It is a quick indicator of whether the object is checked out. When an object is checked out, a user has exclusive access to it, preventing others from making changes to the object until it is checked back in. However, displaying this symbol for every object in a very large assembly (5,000 or more objects) can degrade performance. Turning off the display of this symbol in tree views (assembly trees, attachment trees, and so forth) improves performance. Turn off the display of the symbol by setting the TC_show_checkedout_icon preference to FALSE. Checkout status always appears in the Details view, regardless of how you set the display of the checked-out symbol. If you turn off the display of the checked-out symbol, refer to the Checked Out column in this view to determine the check-out status of objects. To turn off the display of the checked-out symbol: Choose Edit→Options to display the Options dialog box. At the bottom left of the dialog box, click the Filters tab to display the Preferences by Filters pane. In the first Filters box, type as much of TC_show_checkedout_icon as needed to reduce the list of preferences so that the preference displays in the Preferences List. Select the preference from the list. In the Value box, change the value to FALSE. Click Save. Click Close to close the dialog box. Log off your session. Log on again to see the change take effect. The symbol no longer appears to the right of objects in tree views.
