Is virtual calls really slow or it is just bull........? With slow do I mean "slow" as I should notice it, not just some extra nanoseconds or so, that do I not really call slow. Of course should it probably have a negative impact on a critical section/application, but now do I mean a normal program that is normally not limited to CPU power but more network, disk IO and such resources. I wonder because I just have started to use virtual methods in many classes, and is thinking of I should use it together with multiple inheritance. My application should then be much easier to maintain and extend.
Thanks in advance!
