Well, I have just down an interesting investigation (because of some discussion thread in comp.alt.c++.moderated) which also nicely explains why in U++ we are using "const char*" instead of String so often.
#include <string>
void foo(const std::string& x);
void foo2(const char *s);
void Test1()
{
foo("just a test");
}
void Test2()
{
foo2("just a test");
}
Now Test1 has 115 bytes, Test2 12 bytes... (and it is similar for String too).

Quite huge difference. If Test1 is translated to sth like this:
void Test1()
{
const std::string x("just a test");
foo(x);
}
..it is still interesting that creating string object needs 103 bytes more.
