What do you mean "fast"?

I think the other exchanges like Poloniex, Bittrex, will do the same as Binance and Bitmex. Maybe it's because you see the buy and sell order moving faster, so you think that is fast. And if that is what you mean, then if many traders traded on one exchange and trade only for 1 coin, then the price will move faster than usual.

You can check on Bitcoin pair usdt when there is good or bad news, the price will up and down so fast and makes you confuse to place the order. I don't think that it's because the technology but maybe it's because the script that has been used by each exchange will not be the same so it will affect the trading itself.
