When to Change

If sar indicates a great deal of transaction lookaside buffer (utlbmiss) overhead in a very large application, you may need to increase this parameter. In general, the more the application changes the memory frame of reference in which it is executing, the more likely increasing tlbdrop will help performance. You may have to experiment somewhat to find the optimum value for your specific application.
