Hi Melvin, I recommend that you install Globus Connect Multi-User - https://www.globusonline.org/gcmu/ and use Globus Online (www.globusonline.org) to do the transfer.
In case of the transfer you mention below, if you add say '-p 4' or '-p 8' to the globus-url-copy command line, you should get much better transfer rate. That said, you should really be using Globus Online as it does autotuning of the parameters to get good performance.
