- TITLE :Increasing the Performance of MS-DOS-Based Applications
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:
-
- ----------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system, version 3.1
- - Microsoft Windows NT Advanced Server, version 3.1
- ----------------------------------------------------------------------
-
- If you are not satisfied with the performance of your MS-DOS-based
- applications on Windows NT, try the following:
-
- - If the application is in a window and the video display performance
- is slow, try full-screen mode.
-
- - Disable the Compatible Timer Hardware feature in the _DEFAULT.PIF or
- the application's program information file (PIF) under the
- NT-specific section of PIF Editor. Since this feature causes a
- decrease in performance, it should be used only if it is required to
- make an application to run with Windows NT.
-
- - If the application is in a window and seems to pause periodically,
- try disabling Idle Detection in the Advance section of that
- application's PIF.
-
- - If the MS-DOS-based application can be configured for printing,
- choose LPT1, LPT2 over parallel port. Most of the applications use
- Int17 to print when configured for LPT<x>. If you select parallel port
- mode, these applications print directly to printer ports. Parallel
- mode is significantly slower in Windows NT compared to Windows 3.1.
