Thread: slow std::string?

Hey guys, I'm just bored sitting in a comp apps class, and I thought of something (just a passing curiosity). Are std::string's very slow compared to simple char*'s?

Code:

std::string str = "String";
int res = strcmp(str.c_str(), "ABCD");

char* str2[] = "String";  //Much faster, or neglible?
int res2 = strcmp(str2, "ABCD");
