What are the performance implications of using signal-slot in C++?

What are the performance implications of using signal-slot in C++?

Using signal-slot in C++ can introduce some overhead due to the indirection and type safety checks. However, it provides a flexible way to manage events.

How does it compare to traditional callback mechanisms?

Signal-slot is generally more decoupled than traditional callbacks, allowing for easier maintenance and scalability, but it may be slower due to the additional layers.

Are there any benchmarks available for performance comparison?

Yes, there are benchmarks available that show the performance differences between signal-slot and direct function calls. They typically highlight the trade-offs in flexibility versus speed.

What optimizations can be applied to improve signal-slot performance?

You can optimize by reducing the number of connections, using direct connections when possible, or employing more efficient data structures for signal management.
