That's quite unlikely to be the case. settextbuf seldomly makes a
difference for me. Especially if you write to standard output, which
will trigger a flush after every writeln anyway.

Of course it is possible to write a routine which is just as fast as
the one in libc, but I'm not going to spend my time on that (I spent
months on debugging the current routine on different architectures to
get consistent and pretty correct output, and there are plenty of
other more interesting and -as far as I am concerned- important
things to do).
Currently, FPC's float->string conversion is apparently too slow for
him however, so FPC is not useful for him at this time if his main
interest is "speed of converting floating point numbers to string
