The big question would be what should be benchmarked. ZFS is like a big RAM cache. The more RAM the better. You would be surprised how little disk activity there can really be on systems with a lot of RAM as long as synchronous writes are avoided. As a result, some common scenarios mostly exercise RAM rather than the disk channel. Unless you need a higher power CPU for other purposes, a ZFS-based server should focus on maximizing installed RAM.
