Thank you.  Removing those seemed to help significantly.  I am now having issues with removal up to an upper_bound value.
You mentioned "testing with release settings".  How do I enable "release settings"?

Thanks

I strongly suspect this is the problem. Are you doing your performance tests in debug mode? If so, invariant and safe mode (specially the former) have a huge impact on performance.
They shouldn't be used in production, release mode. Try either not using these modes or, better yet, testing with release settings, which in your particular case implies disabling these modes as well. Please report back.
