By using two connections assuming it is possible over FTP to download different pieces of one file at the same time you download the file at 0. Scenario 2 : You're downloading a megabyte file from an FTP server that imposes a download limit of 0. If you're downloading the file using one connection, you download it at 0. Scenario 3 : You're downloading multiple files - let's say two files of megabytes each - from an FTP server download limit disregarded as we've already seen that when a limit is imposed, multiple connections can help.

If you're downloading both files at the same time using one connection per file two connections , you download each of the files at 0. In other words, you only get the two files after seconds. So we conclude that, in this scenario, it depends on whether the files are useful by themselves, or only as a whole. Sorry for not being able to directly address your question, but I think you should first contemplate this scenarios and understand if there's something to get out of multiple connections, in your case.
