Dyamic vs Static Polymorphism in C++ : which is preferable?

Question

I understand that dynamic/static polymorphism depends on the application design and requirements. However, is it advisable to ALWAYS choose static polymorphism over dynamic

Answer 1

A switch is nothing more than a sequence of jumps that -after optimized- becomes a jump to an address looked-up by a table. Exactly like a virtual function call is.

If you have to jump depending on a type, you must first select the type. If the selection cannot be done at compile time (essentially because it depends on the input) you must always perform two operation: select & jump. The syntactic tool you use to select doesn't change the performance, since optimize the same.

In fact you are reinventing the v-table.
