reiserfs is using more CPU than ext2/ext3. It's maintaining its metadata in
balanced tree. Each tree update often requires shifting of some of the data
between or inside of tree nodes. That's where CPU time is going.

Make sure you do not have "CONFIG_REISERFS_CHECK" enabled in you kernel config,
as this enables lots of extra checks in reiserfs code that consume even more CPU.
