I don't know about the exactly memory pattern of string builder but the common string is not an option.

When you use the common string every concatenation creates another couple of string objects, and the memory consumption skyrocket, making the garbage collector being called too often.

string a = "a";

//creates object with a

a += "b"

/creates object with b, creates object with ab, assings object with ab to "a" pointer
