Stacker vs. SuperStor/DS

[Ron_Yee@altabates.com (Ron Yee)]

     I'm relatively new to PC's, and have a general question about data 
     compression:
     
     I have a 701C running PC-DOS 6.22/Win 3/1, and I've almost filled the 
     small (340mg) HD.  SuperStor/DS is on the drive, but not yet 
     installed.  I can pick up a copy of Stacker 3.1 for next to nothing at 
     a local store.  What are the functional differences between Stacker 
     and SuperStor/DS, especially regarding processor overhead and 
     slowdown?  I know that the degree of slowdown varies, but in general 
     percentage terms, how much of a performance hit should I expect (I use 
     the machine primarily for WP, spreadsheets, communications and some 
     minor retouching and viewing of graphics)?  Finally, does anyone have 
     any advice or recommendations regarding install and use of these apps?
     
     Thanks in advance....
