You can always try adjusting the wsize of the snapmirror connection over WAN. Could help...

Well, when you start a snapshot or a snapmirror, it takes snapshot of the vol/qtree to make sure you're sending something consistent.

Are you moving data over a LAN or WAN connection? I find that snapvault sucks rocks over the WAN (45mb/s, 100ms RTT). It's simpler and much faster to use:
lrep_reader bbcp <file(s)> <destdir> lrep_writer snapvault start -r -S <sfiler>:<srcvol> <dfiler>:<destvol>
It's manual, but it works well. I really recommend BBCP (http://www.slac.stanford.edu/~abh/bbcp/) for moving large files efficiently over Fast Wide WAN links.
