Multiplayer lag even on local server

Does anyone else experience lag on photon unity networking? i have been working on photon network for some time now but in every program i make there is always enough lag even when i am running program on local photon server. i dont know if there is something that i am doing wrong or it is supposed to be like this. but i guess lag is more than enough for me.
Does anyone have a solution to it or if there is any way to overcome this lag issue?
