AddBuffers(V1.3) ARP User's Manual AddBuffers(V1.3)
NAME
AddBuffers - Increase the sector cache for system disk
drives.
SYNOPSIS
AddBuffers DRIVE/A BUFFERS/A D2 B2 D3 B3 D4 B4
DESCRIPTION
This command increases the number of disk buffers used by
the system for disk drive access. By increasing the number
of buffers, you can reduce disk access time at the cost of
losing memory to the sector cache (approximately 500 bytes
per buffer). The buffers specified are used for a specific
drive, and do not affect the performance of the other
drives in the system.
Commodore recommends not using more than 25-30 buffers with
the standard filesystem, because more than this does not
improve system performance by much. With the new
FastFileSystem (and a hard drive), more buffers may
increase performance, so more than 30 may be used to good
effect if you have the memory.
The ARP version of AddBuffers allows you to set buffers for
up to four disk drives with a single command line.
EXAMPLE
To add 15 buffers to the sector cache for drive df0 do:
AddBuffers DF0: 15
To add 10 more buffers to df0:, and 20 to hard drive dh0:
AddBuffers DF0: 10 dh0: 20
