Thanks for testing! Would you mind sharing a bit about what kind of test this is, and how you measure the difference? Does it mean that you're throwing a lot of data at the disk, and that you can measure that 'cluster' mode of figuring out where to put the writes has to spend more effort than the 'tetris' mode, and that it limits the write speed? The only relevant difference I was aware of until now is just the placement of the writes. -- Hans van Kranenburg -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
