Have you timed your changes by calling hsv_to_rgb lots of times in
a row ? Trading multiplies for memory fetches is unlikely to be
faster for uncached fetches on current (and even not so current)
hardware. Or have you timed these along with cache invalidation
between calls ?
That said, if you don't call it many times in a row, it's unlikely
to make a dent in one's profile anyway...
