DOCUMENT:Q160656 25-FEB-2002 [winnt] TITLE :Foreground Application Responsiveness Change in WinNT 4.0 PRODUCT :Microsoft Windows NT PROD/VER::4.0 OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 4.0 - Microsoft Windows NT Server version 4.0 ------------------------------------------------------------------------------- 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.
