Search Cache

The Search Cache value is the number of Directory entries ZipStream will 
store in persistent memory measured in thousands.  More Search Cache 
normally means faster operation. 

The default value of 8 (8192) entries is optimal for the average system, 
however, if you have a very large number of files on a compressed drive 
you may want to increase this value. 

The minimum value is 4 (4096) and the maximum value is 64 (65536). 

Having a very large number of Search Cache entries will have the side 
effect of slowing system booting. 

Note:  A reboot is required for this option change to take effect.
