Performance of dir on large file storages

The performance of reading all available data identifiers ("dir") on large file storages (over 140.000 items) really depends on the strategy you took when picking GUIDs. Before doing a Defrag, it takes 1:38 mins just to read all available data identifiers in my index file:

. 145513 (1484 files/sec, 00:01:38 mins) Dir........................................................

Whilst after the Defrag, this takes only 19 secsonds to read all indexes

. 145513 (7658 files/sec, 00:00:19 mins) Dir........................................................
