Is Smash Flash 2 online?

Online is a multiplayer game mode in Super Smash Flash 2 that allows players to battle against other players via the Internet. Utilizing the infrastructure of the McLeodGaming Network, it allows players with accounts to do so over a peer-to-peer connection.

Why is SSF2 so laggy?

In SSF2, the online mode uses peer-to-peer connections in order to get the best performance. However, if a player has a weak Internet connection, the distance between the players is too far, or a player’s computer is not strong enough to run SSF2 smoothly, the game can lag quite a bit.
