iSCSI instead of NFS ?
Because of the overwhelming difference in transfer rate between
them,.... In fact, that's what i read.
That would depend on I/O pattern, wouldn't it? If you have mostly
random I/O then it's unlikely you'd saturate a GigE as you're not
streaming. Well, this is with 3.x. I don't have any experience with
4.x so I guess it's best to test. Everyone's going to have to build up
all their knowledge from scratch with the new software. :)

Cloning Windows images (assuming one VMDK per FS) would be a
possibility as well. Either way, you may want to tweak some of the TCP
settings for best results:

And setting isCSI target is so simple, that i didn't even search
another
solution.
