Don't know what your objects are , but here is an approach that may
help.speed it up.
Keep the bounds of all your objects.
First test all the bounds to see if they contain your point - if they
do, they are a possible candidate.
Now check the candidates using slower full point-in-polygon analysis
to find which of the candidates really contain the point.
This is never going to be fast for 30,000 objects. I cannot see any
purpose for a map with 30,000 objects on it, there is no way to see
them or make sense of them.
