NTFS in Ubuntu is implemented using FUSE (Filesystem In Userspace, see http://en.wikipedia.org/wiki/Filesystem_in_Userspace). Thus file I/O and metadata has to transfer to and fro between kernel and userspace which can create context switching and will consume more CPU than a native kernel based file system. Some anecdotal evidence shows that NTFS using FUSE is similar in performance to other FUSE based file systems (such as ZFS) and there are reports that FUSE based NTFS consumes more CPU than the Windows equivalent.
