I believe I'm a fairly typical Windows user: I have a couple
major Windows applications and a slew of DOS programs. Early
on, I found I got very slow performance when I ran DOS
applications under Windows. If you have the same problem,
here's my solution: Using SYSEDIT.EXE or any other ASCII
text editor, open your SYSTEM.INI file, go to the [386Enh]
section, and add a line with the command PerVMFILES=20. The
'20' reflects the largest number of files that any DOS app
can use at a time; you may wish to use a larger or smaller
value. Save your file, leave your editor, and exit and
reenter Windows. Then watch your DOS apps take off!

Editor's Note: The PerVMFILES setting reserves "private"
file handles for each DOS window, giving your DOS programs
faster access to files. You'll loose a few bytes of system
resources, but that shouldn't cause much of a problem. Note,
however, that you'll see a speedup only in programs that
keep many files open at once, such as relational database
managers.
Make sure of two things if you use this tip. First, make
sure the value you specify is smaller than the number given
in your CONFIG.SYS file's FILES= command. FILES sets the
total number of files that may be open at once in the entire
system (including all DOS windows), so be generous! I
recommend that FILES be set to at least 60 if you're running
several file-hungry applications at once; 30 is a practical
minimum for Windows. Second, make sure the PerVMFILES
command is below the [386Enh] heading and above any other
heading (in SYSTEM.INI, a heading is a line that's enclosed
in square brackets).
If you're uncertain about what editor to use when making
changes to your configuration files, you may want to use
SYSEDIT, an unadvertised program that's bundled with
Windows. SYSEDIT.EXE, a very useful multiwindow
configuration editor, doesn't install automatically as an
icon, so many users don't even know it exists. It opens the
four files you need to configure your system AUTOEXEC.BAT,
CONFIG.SYS, SYSTEM.INI and WIN.INI in four tiled windows on
your screen. To use it, select FileoRun from inside the
Program Manager, and enter SYSEDIT.EXE as the program name.
If you find yourself using SYSEDIT a lot, you may want to
turn it into a Program Manager icon. In order to do this,
select the group window you want SYSEDIT in, then select
File·New·Program Item. In the resulting dialog box, type
System Editor as your description and SYSEDIT as your
command line. When you press <Enter>, the SYSEDIT icon will
appear in your program group.
