Faster way of writing this code: (finding index)

The code I want to optimize is:
index_min = sum( input > quantiles );
where quantiles is a vector of doubles in increasing order. I am using the sum function to find the index of quantiles that corresponds to the value of input. I think the "find" function is actually slower.

Just how much speed do you require? Is this for a real time app, like for video processing? How much slower? Are we talking nanoseconds here?
