FYI some braindead benchmarking, reiserfs vs ext4, kernel 2.6.35-gentoo-r8 Copy same DVD image from internal reiserfs drive to freshly formatted external drive; reiserfs 1m37.530s ext4 3m15.074s Then image copy on that external drive; # time cp CentOS-5.3-x86_64-bin-DVD.iso CentOS-5.3-x86_64-bin-DVD.iso2 # time cp CentOS-5.3-x86_64-bin-DVD.iso CentOS-5.3-x86_64-bin-DVD.iso3 reiser 1m44.719s and 1m51.441s ext4 3m24.337s and 4m30.534s Not that is matters, but create filesystem on 2TB drive; reiserfs 1m17.373s ext4 6m3.421s Didnt see that coming, I guess i'll stick with reiser3....
