Not at all?

My experience in Ada83 on Dec Alpha and IBM RS6000 H/W has been that
standard Ada I/O implementations are _VERY_SLOW_ - writing wrappers
which pragma interface to C library functions can often give huge
performance increases especially if the OS provides 
asynchonous i/o facilities for C.
