You can solve it in a number of ways, the easiest and fastest way is to use FileZilla to transfer files from your seedbox, in the FileZilla settings, you can define how many simultaneous transfers it is allowed to use, set this to a higher number (we recommend 5), in case you are downloading a single file, this will not help, in that case we recommend using BitKinex FTP client instead..
If you use FileZilla, make sure you are using as many connections as possible, by going into settings and setting it to 10:
If this does not work, we offer a FTP Bouncer service, which will send the data from our servers over high capacity links to a server which is located closer to you.
