As you can see, C++ Format has 80% less overhead in terms of resulting
code size compared to IOStreams and comes pretty close to ``printf``.
Boost Format has by far the largest overheads.

IOStreams and printf win here which is not surprising considering that
they are included in the standard library. Tinyformat produces somewhat
larger executable sizes compared to C++ Format. Interestingly optimized
compile time is smaller for C++ Format than for tinyformat and its the
other way around with non-optimized build. Boost Format has by far the
largest overheads.
``libc``, ``libstdc++`` and ``libformat`` are all linked as shared ``libc``, ``libstdc++`` and ``libformat`` are all linked as shared
libraries to compare formatting function overhead only. Boost Format libraries to compare formatting function overhead only. Boost Format
