If I'm not mistaken (and I very well may be!), the diskcachemethod works on a 
directory by directory basis.  If you have a lot of objects in one "flat" 
directory (without subdirectories), it may not help that much.  Alternatively, 
if your volume is spread well (deeply) across lots of directories, then it will 
be more helpful.

Another option would be to use -incrbydate, but that has its own caveats.
