My initial guess would be that you don't have a 6mbps dedicated pipe across the
atlantic and that your packets are competing for bandwidth, thus the reduced
actual throughput.

If you put the boxes side by side, they could easily max a 6mbps link, as such
the problem exists on the network (or the WAN link for that matter).  Check to
see if you have 6mbps dedicated, not only at both ends, but through all the hops
in between.
