According to the wikia the first gate gives a 5 times multiplier to the users physical strength not speed, just strength. Don't know where that number came from, probably from the databook. So like we already saw with Lee, using the first gate severely weakens the user after performing just one technique (i.e primary lotus). That wouldn't be a smart move for kakashi to make because simply increasing his strength wouldn't mean anything if he can't get a decisive blow in.
