This is odd. When I performed tests btrfs and ext4 were both about the same speed for copying a mixture of large and small files to. I was testing them using my laptop card reader though. Tixy: Do you get similar btrfs vs ext4 results using the same card on an x86 host? Is your host 64 or 32 bit?
The results I have kicking around for tests on my PC, which uses a year old 64bit kernel are:
ext4 363s ext3 713s ext2 279s btrfs 208s
This was with a different SD card I think. I'll try and do more like-for-like comparison.
