From my understanding, When your trying to lag someone else unless you have a Great Download/upload speed it's not going to make a big difference. Also, if your lagging someone your sending data to them, which is like uploading something, which kills your bandwidth. Which is why I said unless you have a Awesome download/upload speed your not going to get the results you want, besides using multiple computers on different connecters(DDoS) vs your single computer (DoS)
