Different settings, different speeds

SDL Development
1

I’ve noticed that for a given SDL_init color depth, the speed of blitting varies depending of X color depth settings.

For example if i set SDL_init to 16 bpp, the blitting speed is two times greater if X is also set to 16bpp than 24 bpp.
Is it normal?

That?s okay, because SDL has to convert ( shift ) all the 16bpp pixels to 24bpp.
I think there is no faster way converting between different bpps than shifting.
