    Benchmarks

    [DESCRIPTION]

    Here are some random benchmarks which shouldn't be taken too seriously. They are
    presented to give developers some rough idea what one can expect from Dao regarding its
    efficiency. These benchmarks by no means indicate the performance of these languages in
    real applications.

    Some of the benchmarks are taken from the The Computer Language Benchmarks Game. All the
    tested benchmarks are available here benchmarks;

    The following languages are chosen for comparison,
     Language  Version/Compiler
     Dao       2.0-devel-2013-11-10
     Lua       5.1.5
     Python    2.7.2
     Go        1.1.1
     Java      1.6
     C         Apple Clang V4.0 (-O2)

    The benchmarks are executed on Mac OS X 10.8.4 with 1.8GHz Intel Core i5. In these tests,
    time is measured in seconds (S), and memory is measured in Mega-Bytes (M).

    Note: meteor is a port of the Python meteor program; meteor2 is a port of the C meteor
    program; and DaoJIT did not work on the meteor2 program.

    The followings are a couple of benchmarks to compare Dao to Go.
