I think these results are good enough provided that you can show that some
significant optimizations are available. People can always fall back on raw
streams for time-critical I/O.

Results were :

. compiled with optimisation (-O) :
printf time         : 0m 0.732s
ostream time        : 0m 1.659s,  = 2.267 * printf

stored format time  : 0m 3.541s,  = 2.135 * stream
format time         : 0m 6.434s,  = 3.879 * stream
func_format time    : 0m 9.998s,  = 6.028 * stream

. compiled with debug (-g) :
printf time         : 0m 0.742s
ostream time        : 0m 2.399s,  = 3.231 * printf

stored format time  : 0m 9.653s,  = 4.024 * stream
format time         : 0m19.305s,  = 8.049 * stream
func_format time    : 0m26.525s,  = 11.059 * stream

How do those results sound ? good enough, or not quite ?
