If you try the suggestions recommended here and it doesn't solve your problem, 
I suggest you seriously consider SnapImage. It has it's limitations but restore 
performance from tape is not the issue it's been represented to be here. And on 
a big slow disk with millions of files, there's no faster way to get 
file-granular backups to tape.

SnapImage sorts all the file extents in the restore list  before it starts so 
the restore is done in a single pass. Pieces get restored in tape order and 
assembled on the fly. It's certainly no slower than restoring from a normal 
multiplexed tape.

There are things about it that are a little more cumbersome though so you 
should make sure you really have a need for it before you go that direction.
