Much better, but still not good enough...

How to get the time lower will depend upon what exactly is the new
bottleneck, but this is something you'll need to look into by
profiling the code at your end.

There are high level things you could do as well, such as doing a
round robin update of your objects, or caching the intersection data
so that you reusing some of the traversal data between frames.
