SUMMARY
Performance Monitor in Windows NT version 4.0 does not display the same results as Performance Monitor in Windows version 3.51 when you change the Application Performance Boost setting.



MORE INFORMATION
Windows NT 3.51 and earlier boosts the foreground application responsiveness by boosting the foreground thread priority base. Windows NT 4.0 boosts the foreground responsiveness by assigning a longer timeslice (quantum) to the foreground thread than what background threads receive, not by assigning a higher thread priority.
