Virtual functions performance cost

From Efficient C++ Performance Programming Techniques:
Virtual functions seem to inflict a performance cost in several ways:
  • The vptr must be initialized in the constructor.
  • A virtual function is invoked via pointer indirection. We must fetch the pointer to the function table and then access the correct function offset.
  • Inlining is a compile-time decision. The compiler cannot inline virtual functions whose resolution takes place at run-time.
