============== ========
test name run time
============== ========
libc printf 1.28s
std::ostream 2.09s
cppformat 1.32s
tinyformat 2.55s
boost::format 10.42s
libc printf 1.30s
std::ostream 1.85s
cppformat 1.42s
tinyformat 2.25s
boost::format 9.94s
============== ========
As you can see boost::format is much slower than the alternative methods; this
is confirmed by `other tests <http://accu.org/index.php/journals/1539>`_.
Tinyformat is quite good coming close to IOStreams. Unfortunately tinyformat
cannot be faster than the IOStreams because it uses them internally.
Performance of format is close to that of printf.
Performance of cppformat is close to that of printf. cppformat is [faster on
integer formatting](http://zverovich.net/2013/09/07/integer-to-string-conversion-in-cplusplus.html),
but slower on floating-point formatting which dominates this benchmark.
Compile time and code bloat
