Compression Options

ZSPack, by default, uses a standard set of compression parameters when 
compressing files.  These parameters can optionally be configured by using 
the Warp '/w number' option. 

Currently Warp values of '2', '3', '4', '5', '6' and '7' may be applied. 

Warp 2 

Warp 2 has the following effects: 

 1. Use sparse virtualisation. 

 2. Does not use Grip cache. 

 3. Asynchronous recompression if modified. 

 4. Use default compression effort. 

 5. Use best compression method. 

 6. Use auto algorithm selection. 

Warp 3 

Warp 3 has the following effects: 

 1. Use sparse virtualisation. 

 2. Files *.exe and *.dll placed in Grip cache for default Grip period. 

 3. Asynchronous recompression if modified. 

 4. Use default compression effort. 

 5. Use best compression method. 

 6. Use auto algorithm selection. 

Warp 4 

Warp 4 has the following effects: 

 1. Use sparse virtualisation. 

 2. Place in Grip cache for default period. 

 3. Asynchronous recompression if modified. 

 4. Use default compression effort. 

 5. Use best compression method. 

 6. Use auto algorithm selection. 

Warp 5 

Warp 5 has the following effects: 

 1. File fully virtualised on open. 

 2. Does not use Grip cache. 

 3. Asynchronous recompression if modified. 

 4. Use default compression effort. 

 5. Use best compression method. 

 6. Use auto algorithm selection. 

Warp 6 

Warp 6 has the following effects: 

 1. File fully virtualised on open. 

 2. Files *.exe and *.dll placed in Grip cache for default Grip period. 

 3. Asynchronous recompression if modified. 

 4. Use default compression effort. 

 5. Use best compression method. 

 6. Use auto algorithm selection. 

Warp 7 

Warp 7 has the following effects: 

 1. File fully virtualised on open. 

 2. Place in Grip cache for default period. 

 3. Asynchronous recompression if modified. 

 4. Use default compression effort. 

 5. Use best compression method. 

 6. Use auto algorithm selection. 

The higher the warp value selected, will generally result in higher 
performance when accessing compressed files.  This may also cause larger 
Swapper file space requirements. 

Without a warp option selection, the default selection of Warp 3 will be 
applied.  The default method is recommended in most cases. 

Warp 2 is recommended for infrequently accessed files or for machines with 
low amounts of RAM. 

Warp 4, 6, or 7 is recommended for games etc where access to compressed 
data must occur at the fastest possible rate. 

Note:  A Warp setting above 4 requires much more system resources for 
operation and therefore should only be selected when needed as performance 
may actually decrease in constrained or very active environments.
