Nicely done, but it's not enough to make me switch away from CStrings. I
find std:strings incredibly difficult to work with especially in the MFC
paradigm. You're results are interesting though.

This topic was "buried" in a recent thread here in this newsgroup but with
different subject ("Add ... to long strings"), so I'm trying to resurrect
it here.

I refactored a bit and extended a bit L.Allan's original benchmark,
including also a comparison with STL string class.

The results I have on a VS2008 build (on a Intel Core 2 Duo @ 2.4 GHz and
3 GB of RAM) are the following:

STL std::string : 0.156 ms
CString : 0.395 ms
sprintf : 1.116 ms

So, it seems that actually with VS2008:

- CString operator+= is faster than sprintf()
- STL string class is faster than CString

The VS2008 solution is attached here.
