Parameters

Options for CACHE386 (x is an optional drive letter):

'/OPTIONS[:x]'

Display current configuration

'/STATS[:C|:D]'

Display, clear, or dynamically display statistics

'/LAZY[:x][:ON|:OFF]'

Enable or disable lazy writing

'/MAXAGE[:x]:n'

Change msDataAge to n milliseconds

'/BUFFERIDLE[:x]:n'

Change msIdleBuf to n milliseconds

If no drive (x) is given, the option will apply to all HPFS drives.

Each option may be abbreviated to a single letter, for example:

'CACHE386 /B:D:1000'

(sets BufferIdle to 1000 for drive D)

Adding the parameter /STATS will display the statistic usage cache usage. This will help you to size the cache to a size where the minimum sized cache achieves the maximum hit rate.
