I have table with some fields that the value will be 1 0. This tables will be extremely large overtime. Is it good to use bit datatype or its better to use different type for performance? Of course all fields should be indexed.

Officially bit will be fastest, especially if you don’t allow nulls. In practice it may not matter, even at large usages. But if the value will only be 0 or 1, why not use a bit? Sounds like the the best way to ensure that the value won’t get filled with invalid stuff, like 2 or -1.
