Here's some feedback:

1. It seems turn restrictions are not taken into account in the routing?

2. It seems that the internal routing graph has too few nodes from where
you can start or end. I think this might be a result of the optimizations
you have performed to make the router fast. So if you wanted to route to a
POI along a one-way street, you might get routed to the point at the end of
the one-way street and the route does not pass through that one-way street.

Here's an example to make the second issue clearer:

I would expect the route to pass along the one-way street.
