This is not true for all ASICs.  Some ASICs choose to incur the penalty in a different way, e.g., by halving the prefix tables.  The prefix table is then duplicated so that uRPF SA and forwarding DA lookups can happen in parallel.  What kind of penalty is incurred is a question worth asking the equipment vendor.

Agree with this - the implementation can vary between vendors and between hardware.

Best to test your specific platform, to be sure.
