Are you sure these numbers are correct?
Note, that %cpu numbers for fuse filesystems are inherently skewed,
because the CPU usage of the filesystem process itself is not taken
into account.

So the numbers are not all that good, but

Wow! Userspace and still that
CONFIG:

Kernel was 2.6.21 or 2.6.22, did these awhile ago.
Hardware was SATA with PCI-e only, nothing on the PCI bus.
ZFS was userspace+fuse of course.
Reiser was V3.

Wow! Userspace and still that efficient.
Extrapolating these %cpu number makes ZFS the fastest.
