On my cable connection, DAP makes a big difference about half the time. Sometimes it is much faster, sometimes it is not... But I like it most because you could line up a queue of things to download. Say you are downloading a set of 50 .RAR files, you can just click on all 50 of them real quick, and they will get downloaded. Not using DAP, you would have to click on a couple, wait for them to finish, click on a couple more, wait...
