Please note that the file you are going to download (bootstrap.tgz) is 42540 bytes big. On an average ADSL connection, it may take long to download it (about less than a minute at 1Mbps).
Moreover, if you use one of the provided Virtual Machines to perform your analyses, then you don't need to download datasets manually, because the VM will fetch all the necessary file chunks via the XRootD protocol.
Manual download of files via HTTP is only necessary if you would prefer not to use the XRootD protocol for one reason or another.
