FWIW i finally re-ran my tests (CPU is 64 bit dual core Intel 2.4GHz);
Copy DVD iso from Internal drive (reiserfs) to external drive
reiserfs 1m24 1m23 1m23 1m22
ext4 1m39 1m25 1m25 1m25 remount 1m26 1m23 1m23 1m22
btrfs 1m22 1m22 1m22
btrfs+comp 1m20 1m21 1m20 1m21
Copy DVD iso on external drive
# sync; time (cp CentOS-5.3-x86_64-bin-DVD.iso
CentOS-5.3-x86_64-bin-DVD.iso2; sync)
reiser 1m52 1m52 1m52
ext4 1m43 1m43 1m43 1m44 remount 1m33 1m33 1m33 1m42
btrfs 1m42 1m41 1m41 1m45 remount 1m46 1m41
btrfs+comp 1m34 1m33 1m34 (im guessing the driver is clever enough not to
uncompress and recompress)
