great. now were down to 7-8% just FYI: ive retested with max_inline=0 but with leafsize=64K this time: # mkfs.btrfs -l 64K -L root /dev/sda2 ... real 4m45.878s user 1m44.730s sys 1m7.226s thats 2% slower for this one test (no big deal really) # btrfs filesystem show Label: 'root' uuid: dd2951da-2529-4320-a952-e692ea5bdbc3 Total devices 1 FS bytes used 11.37GB devid 1 size 232.63GB used 13.04GB path /dev/sda2 Btrfs v0.20-rc1 # btrfs filesystem df /mnt/point/ Data: total=11.01GB, used=10.89GB System, DUP: total=8.00MB, used=64.00KB System: total=4.00MB, used=0.00 Metadata, DUP: total=1.00GB, used=487.94MB Metadata: total=8.00MB, used=0.00 (1024*10.89 + 2*487.94) / 1024 = 11.84GiB still around 7-8% now lets see what everyday use with max_inline=0 and leafsize=64K feels like :) Ahmet -- 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
