At 2s difference it's fair to say that a user is going to notice. Maybe even at 200ms. But at 20ms? I'm not sure that counts. I know it's just a fabricated num

At 2s difference it's fair to say that a user is going to notice. Maybe even at 200ms. But at 20ms? I'm not sure that counts. I know it's just a fabricated number but the point is that the server you're running on won't make a difference to the user experience. And, probably in the case of the differences were talking in these machines, a user would never notice it. Edit: meant to say, I agree with you.
