* Is there a way to increase the speed of the directory access
routines without modifying libtiff?
No.
* Are there other features of libtiff that we can use instead of
directories?
Not sure what this means, but probably no.
* Do you have any other suggestions?
Construct a private tag that has a table of contents of all the images
in each file and use that to locate each IFD. I believe the latest
code on sgi.com includes a call to let you set the current directory
given a file offset; this was added for the SubIFD support.
