I wrote some tests for comparing the ATL vs. STL string performance.
This simple C++ code tests inserting strings into an STL std::vector, and then sorting the aforementioned string vector.
Both ATL’s CStringW and STL’s wstring are tested.
Building that code with VS2015 results in the STL’s std::wstring class winning for both the general case and for tiny strings (in this case the STL’s small string optimization (SSO) determines a huge performance increase over ATL’s CString).
The main C++ testing code can be found in the Test.cpp source file.
