- SUBJECT: Tune-Up Tips To Run Windows Faster
-
- The following are tips for running Windows at a faster speed.
-
- 1. For faster performance in Windows, load your system with
- extended memory, and start using a disk-caching program.
-
- 2. If you regularly run two or more Windows apps together on a
- system with less than 4M of RAM, invest in more memory chips.
-
- 3. Include a line in your CONFIG.SYS file for a disk cache so
- that your disk drive does not spin its wheels with unnecessary
- disk activity.
-
- 4. If your processor is 386 or 486 and you have at least 2M of
- memory and you seldom run non-Windows applications, try
- running in Standard mode. You can do this by typing WIN /S or
- WIN /2 at the DOS command line.
- a. Running in 386 Enhanced mode offers many advantages for
- working with DOS apps, but it does nothing for Windows
- programs--it may even slow them down.
- b. For DOS 5.0 users that use EMM386.EXE to load TSRs and
- device drivers into high memory, Windows will refuse to
- run in Standard mode. You'll have to choose between the
- extra conventional memory or the quicker Windows
- performance.
-
- 5. Keep your hard disk optimized by running a defragmentation
- utility on a regular basis. An optimized hard disk lets your
- system store larger amounts of data in contiguous disk
- sectors, reducing the amount of time Windows spends reading
- and writing swap files.
-
- 6. If you run Windows in 386 Enhanced mode and can afford the
- disk space, set up a permanent swap file. This allows Windows
- to bypass normal DOS file I/O routines and move information in
- and out of memory more quickly.
- a. The drawback is that the disk space assigned to a
- permanent swap file cannot be used for other proposes,
- even when you're not running Windows.
- b. To create or delete the permanent swap file, start
- Windows in Real mode and run the SWAPFILE program.
- Windows will recommend an optimal size based on available
- disk space. Try 5M for starters, and if you don't see a
- lot of disk activity as you work, you might be able to
- reduce that figure somewhat.
-
- 7. In the program information files (PIFs) you create to run
- non-Windows apps in 386 Enhanced mode, don't select any of the
- Monitor Ports options. Most programs don't require them, and
- leaving them unchecked will improve performance. Windows'
- default PIF has one of the monitor Ports options selected. It
- is a good idea to create a PIF for every DOS app you use.
- 8. If you run Windows with a Super VGA, 8514 or other
- high-resolution driver, consider switching back to normal VGA.
- The same advice applies to using a 256-color driver instead of
- the 16-color variety. For everyday wordprocessing, you might
- use ordinary 16-color VGA, reserving the more colorful
- displays for desktop publishing and other apps that can really
- benefit from additional colors.
- 9. SMARTDRIVE.SYS will by default use 1024 or 2048 for the
- maximum cache size which can slow you down on a machine with
- only 2 or 4M of RAM. The reason is that even though the disk
- cache is larger, it can force more disk activity by reducing
- the amount of RAM available for WINDOWS and its applications.
-

- Optimizing Windows (Speed)
-
- More RAM usually means More Speed:
- The most valuable resource running under the Windows environment is
- RAM. Whether you have an 80286, 80386 or a 80486 based machine the
- best way to increase your overall speed and performance is to add
- more RAM. With an 8088 or 8086 based CPU, adding RAM will help to
- some extent but you will always be limited to running in Real mode
- (remember, WPWin requires 2M of RAM (4M recommended) and you must
- be able to run in either Standard mode or 386 Enhanced mode.)
-
- Set up a Disk Cache:
- Adding more RAM helps the speed of Windows (and thus WPWin 1.0),
- but only if you use it properly. The best use of your extra RAM
- would be to set up the right-sized disk cache. Windows comes with
- a disk caching device driver called: Smartdrive (SMARTDRV.SYS), but
- Windows usually sets it up in a way that is a compromise to most
- users. The size of your cache should be as big as you can make it,
- without eating into the memory requirements of Windows or WPWin.
- The recommended size is to allot no more than one-third of your
- memory as cache, but maintain a minimum of 1.5MB for Windows and
- WpWin (e.g., on a 4M CPU, the CONFIG.SYS file should read:
- DEVICE=SMARTDRV.SYS 1536 512. This means that the cache will be no
- bigger that 1536K and no smaller than 512K). These numbers will
- work well for word processing and simple desktop publishing.
- Although Smartdrive doesn't offer the level of control of some
- caching programs like Super PC-Kwik) it's better than nothing.
-
- Fast Hard drive - More Speed:
- Along with lots of memory, Windows and WPWin (as well as any
- program) like fast hard drives. When you move from a typical 28 to
- 40 ms AT-class drive to a 23ms or faster drive, you will increase
- your speed by at least 15 percent!
-
- Faster Video:
- Computers, operating systems and programs are only as fast as their
- slowest link, a slow 8-bit EGA board, although sufficient to run
- Windows and WPWin, can slow your entire system down to a crawl. The
- ideal video system would be a 16-bit VGA adapter with built in
- video RAM (again the more the better). Replacing an old VGA or EGA
- adapter with a new VGA 512K video RAM cache will improve speed by
- 15 percent or more.
-
- Simple Wallpaper:
- Although wallpaper can be exciting it takes up RAM, and as we
- discussed above, RAM means speed.
-
- Disk Housekeeping:
- Windows and WPWin both create dozens of temporary files to swap
- information to and from. If Windows or WPWin do not have a lot of
- contiguous free disk space to work with, they won't run as fast.
- Run a disk reorganizer periodically, even if it does not look like
- you have any fragmented files. The idea being that you want to keep
- large, contiguous areas of hard disk space free.
-
- (Note: BE CAREFUL WHICH DISK ORGANIZER YOU ARE USING-MAKE SURE IT
- IS COMPATIBLE WITH YOUR HARDWARE. ALSO, DO NOT RUN THE DISK
- DEFRAGMENTER FROM WITHIN WINDOWS.)

- If WPWin is not running optimally, have them try the following
- steps:
- 1. Decrease the number of Windows applications which
- are running before launching WPWin.
- 2. Increase the file handles in the CONFIG.SYS file.
- For example, if the command reads FILES=20, change
- it to read FILES=30 (Microsoft recommends at least
- 30 file handles be allocated. Remember to reboot
- after making these changes.)
- 3. Decrease the SMARTDrive command values in the
- CONFIG.SYS file. For example, if the command reads
- DEVICE=SMARTDRV.SYS 2048 1024, change it to read
- DEVICE=SMARTDRV.SYS 512 256 or DEVICE=SMARTDRV.SYS
- 256 128. For more information on using SMARTDrive,
- see Using SMARTDrive under Optimizing Windows
- (Chapter 13) in the Microsoft Windows User's Guide.
- 4. If the customer is using a program which condenses
- data as it is stored on the hard drive (e.g.,
- Stacker, DRDOS Superstore), redirect the temporary
- files to a hard drive where information is not
- automatically condensed. (Note: this does not
- apply to data compression performed by hardware such
- as "RLL" drive controllers.)
- 5. Minimize program groups so there are fewer icons.
- 6. Disable the Ruler, Button Bar, and Vertical and
- Horizontal Scroll Bars as defaults for starting the
- program.
