Any suggestion how I can do it fast and efficient when I have many points and many polygons? Looping over all is very costly.

You can use postgis to store your polygons and use one of the built-in functions of the server.

@mah65 If the distribution is very imbalanced (e.g. most points are in a few countries), ordering the polygons by order of most frequently seen can greatly increase performances. You can sample a number of random points from your data to find the most efficient ordering.
