Indeed you need to use WebsocketProvider, it gives you opportunity to receive notification instantly after node synchronization.

var web3 = new Web3(new Web3.providers.WebsocketProvider('wss://ropsten.infura.io/ws'));

var myContract = new web3.eth.Contract(<abi>, <address>);
myContract.events.allEvents({ fromBlock: 'latest' }, console.log);
