Just to go on this subject : a colleague (following my suggestion :)
tried to create 1 billion files in the same XFS directory.
Unfortunately the directories themselves don't scale well that far :
after 1 million files in the first 30 minutes, file creation slows down
gradually, so after 100 hours we had about 230 million files. The
directory size at that point was 5,3 GB.
Now we're starting afresh with 1000 directories with 1 million files
each :)
