Please try increasing the values of MAX_ARC_LENGTH and MAX_LINE_LENGTH
and see if that improves things. I would not expect MAX_LINE_LENGTH to
make a difference as that only influences lines not routable ways.

If the reduction in MAX_ARC_LENGTH is causing your routing to become
worse, that's going to conflict with the issue Marko reported.

Cheers,
