Do you have a unit test for this to show it going faster? The reason I
ask is there is a GPFS option for the file system
allowSambaCaseInsensitiveLookup
which I think does something similar but IBM don't document it. It's one
of their magic/secret options. A ready built test case would be useful
in working out how it works/what it does...
