Looking ethgas.info to know more with your gass setting transaction, you must match between ethgass.info and with your gass setting on uniswap or sending your coin in metamask. They will three kinds transaction way, first most faster where you need pay higher fee and you can use starndart with normal fee and using cheapest for lower fee but your transaction take long time for receiving. I use second way when sending coin from metamask, myetherwallet to get lower fees and look faster than third way for sending coin.
