Directory hashing slows down operations that do linear sweeps through the filesystem reading every single file, simply because without dir_index, there is likely to be a correlation between inode order and directory order, whereas with dir_index, readdir() returns entries in hash order.

thank you for the awareness training. Than mutt should be slower, too.
Maybe I should repeat that tests.

Only if you read every single file in each directory every time. I thought mutt did header indexing and thus didn't need to do that.
