Static versus dynamic binding trade-offs

Short answer

Static binding fixes function calls at compile time (faster, no overhead), while dynamic binding resolves them at run time via vtables (slower, uses extra memory). The trade-off is between efficiency and the flexibility/polymorphism dynamic binding provides.

What are the primary trade offs between static and dynamic binding?

Static binding (early binding) fixes the function to be called at compile time; dynamic binding (late binding) fixes it at run time through virtual functions.

PointStatic bindingDynamic binding
SpeedFaster, direct callSlower, call through vtable
MemoryNo extra memoryExtra vptr per object and a vtable per class
FlexibilityLow, type fixed at compile timeHigh, supports polymorphism
Error detectionEarly, at compile timeSome errors appear only at run time
InliningPossibleGenerally not possible

So the trade-off is efficiency and early checking (static) against flexibility and extensibility (dynamic).
