I had something like that in the back of the head, but all of - xfs block sizes 512, 1024, 2048, 4096 - ext4 block sizes 1024, 2048, 4096 - btrfs block size 4096 ran your test program well.
The block size != the ideal I/O size. Block size is the *minimum* I/O size But using the stat -c "%o" call on my mounted partitions, I see:
The optimum IO size "%o" is influenced by the fs block size option, which is why I went through a few values. Nothing more, nothing less :)
Did you specify a size & width?
