- Performance Pack Utility
- Version A.01.01
-
- The Performance Utility program (PERF) displays available memory in the system
- while running under Microsoft Windows 3.0.
-
- Installation and Execution:
-
- - Copy the PERF files (PERF.EXE, PERFLIB.EXE, and PERFICON.FON), to your
- Windows directory.
- - Run PERF.EXE from the Windows directory by double-clicking on the name of the
- application.
-
- Performance Tool Window:
-
- The main window of the Performance Utility continuously displays the currently
- available free memory under Windows. It is updated once per second, both when
- the window is opened and when iconized. It displays the following information:
-
- nnnK Below-the-Line (current available below-the-line memory)
- nnnK Perf [Performance Tool] (current available memory in the application
- bank and the name of the selected application)*
- nnnK Current Swap Area Size (current swap area size of the selected
- application)*
- nnnK Maximum Swap Area Size (maximum swap area size)
- nnnnK Expanded Memory at xxxx (current available expanded memory)
- (xxxx is the EMS Line address)
- nnnK Available from SmartDrive (current available expanded memory that can be
- borrowed from SmartDrive)
-
- *This information pertains to the application that is currently selected in the
- Memory window. When you first start the application, PERF is the selected
- application. If you want to select a different application, refer to the
- Memory window section below. The rest of the information listed pertains to
- the system and does not change when different applications are selected in the
- Memory window.
-
- When PERF is iconized it displays:
-
- nnnB (current available below-the-line memory)
- nnnK (current available memory in the selected
- application's bank)
- XXXX (the first four characters of the selected
- application's Window Class name)
- nnnn (current available expanded memory)
-
- PERF main window has two pulldown menus:
-
- - Action menu: used to select the Memory or Timer windows. It is also used to
- select the About box and the Windows version information box. The Windows
- box tells you the version number and whether it is a debugging or a non-
- debugging version of Windows.
- - Settings menu: if the Memory command is selected, then the main window
- displays information on the application that is highlighted in the Memory
- window. If the Focus command is selected, then the PERF window will display
- information on the application that has user focus.
-
- Memory Window:
-
- This window displays a list of the currently active applications. Information
- about the application selected in this window is shown in the main PERF window
- if the Memory command from the Settings menu of the main PERF window is
- selected. If the selected application is then closed, then PERF reverts to
- displaying information about itself. Changing the selected application does
- not change the system information such as below-the-line memory, expanded
- memory, or the EMS line address.
-
- Menus in this window provide additional functions for application developers.
- These allow the developers to allocate and free memory in different block
- sizes, discard memory blocks that are marked as discardable, and set different
- swap area sizes. Detailed explanations are provided in the HP NewWave Developer
- Kit.
-
- Timer Window:
-
- This window can be used to time activities in the system. The "manual" mode
- functions as a stopwatch. "Auto" mode allows the user to measure the time it
- takes to perform an action in the system. For example, you can find out how
- long it takes you to open an application window. To do this, just select "Set"
- in the Timer window and then double-click on the icon or program. When the
- window has been opened, the Timer window shows the elapsed time. Note that
- once you have "Set" the timer, anything you do in the system will cause it to
- measure that activity. So if you single-click on a different window before you
- double-click on the application that you want to open, the single-click will be
- the activity that gets timed.
