        Measurements related to the performance of the BOOST_METAPARSE_STRING macro.
      
128 strings with increasing length. Measured on a Linux-3.13.0-24-generic-x86_64-with-Ubuntu-14.04-trusty host with 16 GB memory. Compiler used: gcc 4.8.5.
           
        
Increasing number of strings with 64 length. Measured on a Linux-3.13.0-24-generic-x86_64-with-Ubuntu-14.04-trusty host with 16 GB memory. Compiler used: gcc 4.8.5.
           
        
100 one character long strings with increasing maximum length. Measured on a Linux-3.13.0-24-generic-x86_64-with-Ubuntu-14.04-trusty host with 16 GB memory. Compiler used: gcc 4.8.5.
           
        
        Parsers work at compile-time, thus their performance affects compilation
        speed. This section shows measurements of compilation time using Metaparse.
        The measurements were done on a Linux laptop with an 1.6 GHz Atom processor
        and 1 GB memory. The measurements were done using GCC 4.6.1 with -std=c++0x and no optimisation. Compilation speed
        was measured using the time
        utility.
      
        To measure a non-trivial parser, the printf
        example program were used for measurements. Here is a list of the printf calls and their compilation speed
        (user output of time):
