TITLE: Advanced Gravis Tech Note #11
AREA: MEMORY MANAGERS
DATE: January 22, 1993
KEY WORDS: MEMORY MANAGERS SLOW DOWN
SUBJECT: Do not use third pary memory managers where possible
Although many of these memory managers are highly rated and work quite well
in most cases, they do steal precious time. A recent PC Magazine test of
memory managers confirms this. As with EMM386.EXE, memory managers
require some knowledge to configure for maximum performance. Many memory
managers sacrifice performance for convenience. In other words they do some
wonderfull things, like maximize memory allocation automatically, but they
take time to do this. Below is a typical CONFIG.SYS for a 4 meg system
using MS DOS managers.
DEVICE=C:\DOS\EMM386.EXE 1024 FRAME=E000 RAM
The \DOS\directory path should be replaced with \WINDOWS\ if windows is
installed. The Windows versions are better in most cases. This
configuration will give MOST 386 or better systems about 634k of available
main memory, 95k of upper memory for SBOS, mouse drivers etc., 1 meg
of expanded memory and about 2 megs of extended memory. As minimal
as it looks, this configuration will satisfy the needs of most games. Some
games want no EMS at all. Simply delete the last line in the above example.
A separate bootable floppy disk can be created just for games. Read the
section on optimizing the system in the DOS reference manual.
