Hi all,

I have one suggestion , i think the low rate is because of intermediate
routers between 2 sites.

You can also try. The other way, disable the ipsec tunnel between twi sites
and have only simple forwarding.

It can give some clue of either delay with network path(can not be avoided )

Yes, I checked this too and the upload is not saturated at all (there is
only a slightly change of 0,75 Mbit/s).
