That seems to be a reasonable conclusion. BTFW that my million file test directory uses this sort of file naming, but it has only been written once. When making data multi-access safe, often it is easiest to mark old data entries as unused while retaining the allocation. At some later time when it is convenient to do so, these old entries may be made available for reuse. It seems like your algorithm is causing the directory size to grow quite large, with many stale entries. Another possibility is that the directory is becoming fragmented due to the limitations of block size. The original directory was contiguous, but the updated directory is now fragmented.
