Someone may think a slow typing keyboard may be a software issue. One might think if the keyboard is typing slow, it must be a software issue and not a hardware issue. In some cases this may be true, but in some other cases, this may not be true. In this situation, the cause of a slow typing keyboard was caused by a hole in the keyboard ribbon cable. The hole in the ribbon cable was not obvious and was slightly hiding underneath the flap of the cable.
These are cables and hardware from a Dell Precision laptop computer
