You mustn't belive in Benchmarks :-). Try it empirically, and you will see,= =20 that for big files, Reiser4 is much faster, then ReiserFS was. Some example Deleting a 6,8GB DVD iso image (average of 10 tests): ext3 14,15 sec reiser3.6 12,67 sec reiser4 1,23 sec Deleting 3 GB of MP3 files (4MB average file size, 10 tests): ext3 11,91 sec reiser3.6 4,56 sec reiser4 1,86 sec Marcel =2D-=20 =DCdv=F6zlettel -- Mit freundlichen Gr=FCssen, Marcel Hilzinger
