DOSBox isn't exactly very accurate. 315 cycles is just a ballpark figure, but how it actually compares to a real 8088 depends on the instruction mix used by the game.
In DOSBox, all instructions are equally fast. On a real 8088, there are huge differences in execution speed between instructions.
That's true. They "feel" to fast, but I would need to try them on a real 8088 to know if that is a problem with the CPU or a just a problem with the game.
