Hmm... I really haven't noticed much speed diffrence on my side......... tho there are occationally times i click thinks and it just spins it little wheel around and around. and when i click on it again, it will normally go. but i just thought that was my internet itself, lol because it's doing stuff like that off and on for many sites.

EDIT: Too bad you can add your own DDos into the system that sends out to anyone who tries to DDos the server. If a lot more people did that, I think it would stop a lot of the malicious hackers from doing things such as that.
