snapmirror window_size

I have an initial QSM running over the WAN and the snapmirror is running rather slow.  I increased the snapmirror windows_size on the source and destination Filer.  Comparing the sysstat network outbound on the source remains the same as before the window size increase.  Does the snapmirror window_size setting take affect on active snapmirror?  Or do I need to restart the QSM? 

This is the initial QSM so I'm not sure if I abort QSM it will be in 'restartable' mode and continue where it was aborted when I reinitialize the QSM again.

thanks,.

Hi,

Since you are running SM for the first time, you will have to reintialize the snapmirror for the window size to take into effect.

New TCP window size takes effect only on new connections. You cannot restart initial transfer. Unfortunately (I wish we could).
