Before, I never used to Lag on MCSG. I got such good connection that some people think I hacked. Now..it's the total opposite. I am on Vacation right now and I don't know if it's the internet, but last round, everyone had 1 bar of connection. I've lagged out so many times I can't stand playing MCSG anymore. People say that you are still working on DDOS or whatever it's called but the lag is so powerful that it crashes my Mac. I have optifine for 1.7.2 and people say that it reduces lag but I think it's a little worse. I checked the update 1.7.4 and the update says that it gets rid of the lag. It does however, it still lags a lot.
I hope you fix the lag
