Find the closest coordinate from a set of coordinates

I have about 1000 set of geographical coordinates (lat, long).
Given one coordinate i want to find the closest one from that set. My approach was to measure the distance but on hundreds requests per second can be a little rough to the server doing all that math.

What is the best optimized solution for this?

You will want to use the 'Nearest Neighbor Algorithm'.
