Probably:
(do ((i 0 (+ 1 i))
(l (length v)))
(>= i l)
(float-vector-set! v i (f (float-vector-ref v i))))
Obviously substituting int-vector-* or byte-vector-* if appropriate.
That said, if performance is really important, I might just write the code in c.

Hi all, I'm mapping some transforms over vectors in a part of the code that I
need to have run as efficiently as possible. I'm hoping someone can tell me
what the fastest running approach to this is. I would like to leave the data as
vector as it is used in a framebuffer at the C level.
thanks!
