On either the source or destination storage system, enter the following command:
snapmirror throttle n [system:] path
n is the new maximum transfer rate in kilobytes per second. A value
of zero (0) disables throttling.
system is the destination storage system. Use this variable if you are executing the command on the source storage system.
path is the destination path. The path can be the /volume_name or /vol/volume_name/qtree_name

Are you going over a LAN or WAN connection to the remote side?  And if
over the WAN, how long is your ping RTT time?  The longer the WAN
link, the poorer SnapMirror/SnapVault works, even though they say they
have a 2mb TCP Window Size by default.
