Make sure your ports are forwarded. Either that, or you might just have slow internet. Also, don't use the CD anymore to play the game, it could be a scrach on the CD.

I think you have dial-up.

Firewall, Router, NAT?

Firewall/router blocking ports = you can't do stuff, not lag.

 

Anyways ya, this is STARCRAFT, you don't need a fast computer at all for it.

All you need is a decent internet connection. It doesn't even need to be high bandwidth. Just low latency.
