Buffers
Setting the number
of disk buffers
Buffers
Purpose:
Allows you to set the number of disk buffers that ms-dos allocates
in memory at the time you start the system.
Syntax:
buffers=x
Comments:
The x option is the number of disk buffers, from 2 to 255. A disk
buffer is a block of memory that ms-dos uses to hold data when
reading or writing.
The default number of buffers is 2. But for applications such as
word processors, a number between 10 and 20 provides the best
performance. If you plan to create a lot of subdirectories, you may
even want to increase the buffers value to between 20 and 30.
Remember, though, that buffers take up space in memory, so you
should not increase their number to a value greater than 30.
Example:
To create ten disk buffers, put the following line in your
config.sys file:
buffer5=10
