WOW! That is insanely fast. Are you sure its not 35 Mbps (Mega bits!!)? Google Fiber that everyone covets is 1 Gbps (Giga bit per second) or 1024 Mbps or 128 MBps.
At 35 Mbps it would take a little less than 7 minutes to transfer. That is assuming constant speed. Can you copy the folder from the machine in London to the machine in New York in under 7 minutes?
At 35 MBps it would take under a minute!

I'm not sure why there would be that much overhead with SVN, I guess it does no caching. One the plus side, you only have to check out once. ;)
Have you tried to check out some large public stuff? For example, check out the subversion repository and see how long that takes.
Was the command line checkout time any different?
