Are Exceptions in C++ really slow
...
The main model used today for exceptions (Itanium ABI, VC++ 64 bits) is the Zero-Cost model exceptions.
The idea is that instead of losing time by setting up a guard and explicitly checking for the presence of exceptions everywhere, the compiler generates a side table that maps ...
C++ unordered_map using a custom class type as the key
...const Key' to 'size_t' c:\program files (x86)\microsoft visual studio 10.0\vc\include\xfunctional. I am guessing that the compiler is not finding my hash method? Should I be adding anything to my Key.h file?

Is it possible to print a variable's type in standard C++?
...eid(ci).name() << '\n';
For me outputs:
i

int
I.e. the const is gone. This is not a QOI (Quality Of Implementation) issue. The standard mandates this behavior.
What I'm recommending below is:
template <typename T> std::string type_name();

What techniques can be used to speed up C++ compilation times?
...files as one translation unit is faster (at least in my experiments with MSVC and GCC) and generates smaller binaries. I also suspect that the compiler is given more potential for optimizations (since it can see more code at once).
This technique breaks in various cases; for instance, the compiler ...
