Each FTP session has a control and a data connections.

What happens is the following:
a) an established control FTP-connection is closed immediately just after a
file transfer is accomplished;
b) an established data FTP-connection is not closed after transfer, is kept
during sleeping time and goes closed
only after a new data connection is opened;

Therefore, it might be, that you can test with a 1/2 capacity due to the
described above behavior.
Hope, this is a temporary workaround for you.
Thanks for your testing.
