Google still is working but .. (from my bookmarks):

http://cmynhier.blogspot.com/2006/05/zfs-io-reordering-benchmark.html
http://cmynhier.blogspot.com/2006/05/zfs-benchmarking.html

also some other interestig numbers can be founnd on:
http://milek.blogspot.com/2006/08/hw-raid-vs-zfs-software-raid-part-ii.html

Probably more can be find on looking for zfs+benchmark on 
http://blogs.sun.com/

IMO real power ZFS shows on growing number if phisical devices so don't 
look so close on this kind of documents because usualy it was prepared on
