Changing the Turbo File Allocation Table (FAT) Wait Time for Faster
Reads
5
Increase the value of Directory Cache Buffer Non Referenced Delay.
This parameter specifies how long a directory entry must be cached
before it can be overwritten. Increasing this value causes the system to
allocate more directory cache buffers and thus speeds up directory access.
If the parameter is currently set to the default value of 5.5 seconds, try
setting the value to 60 seconds.

When a program randomly accesses a file that contains more than 64 file
allocation table (FAT) entries, the file system builds a turbo FAT index for the
file so that the information in the file can be accessed quickly.
The Turbo FAT Re-Use Wait Time parameter specifies how long a turbo FAT
index remains in memory after the indexed file is closed. When the turbo FAT
index is in memory, files can be opened and information accessed faster.
If network users frequently access files larger than 64 blocks, use this
procedure to increase the time the index is kept in memory.
