FASTOPEN

Purpose:     Sets the number of buffers for organizing a fast file search
             cache.

Syntax:      FASTOPEN = xx
             Where, xx - ranges from 4 to 99 and defines the number of
             buffers.

By default:  FASTOPEN = 4

     With a complex directory structure, the system has to look through a
significant number of directories when searching for a file deeply located
and if path to this file is not found in any of the buffers, the number of
which is set by the FASTOPEN. Each buffer takes up about 80 bytes of system
memory. Maximum values for the number of buffers should be used when working
with file-extensive applications such as DBMS.
