Question

which I/o functions are fastest??

Answer 1

What language?

Answer 2

Hmm...
Reading from a file will be faster than reading from a server in Siberia, but that's kind of obvious.

Buffered I/O can potentially be faster since it reduced the amount of system calls, but if you are writing huge amounts of data you'll want raw I/O nevertheless.

That's all I got I think. :D

Answer 3

any language i an asking about in all languages
