No easy to answer, jfs and xfs are both good file systems, that's why I am using both on my server at home. JFS on my root partition and backup storage space (250.000 files of all sizes, 900GB) because it uses very little cpu and is very fast. Low cpu usage was important for me, because my backup space is encrypted with cryptsetup/LUKS. On my media storage (recordings, movies, only big files: 500MB to 15GB) I use xfs because of it's delayed allocation which helps to avoid fragmentation. With xfs_fsr xfs also brings it's own defragmentation utility. Speedwise I would they that they are both at about the same speed, but I cannot give you exact numbers. xfs however uses more memory (because of the delayed allocation) and if your server suddenly loses power you can lose data. Hope that helps you, greetings from germany Michael
