Real size vs. Allocated size...

We are storing "millions" of small TIFF images in the IFS. 

After doing this for a couple of months we have noticed that they are taking
up much more space than originally planned...

When I look at the attributes for one of them I see this:

Size of object data in bytes . . . . . :   33936
Allocated size of object . . . . . . . :   65536

OS/400 HELP tells me that "allocated size" is:

The number of bytes that have been allocated for the object.  The      
allocated size varies by object type and file system.  For example, the
allocated size includes the object data size as well as any logically  
sized extents to accommodate anticipated future requirements for the    
object data.  It may or may not include additional bytes for attribute 
information.                                                           

I'm not completely sure if the allocated size is taking up "real" disk
space... 

These files do not need additional space allocated. There are what they are
and will not grow in size... 

Does anyone know how I can make the allocated size equal to the real size,
when I create new objects like this in the IFS or do I even have to worry
about this?
