There are some cryptocurrencies that are ahead of traditional systems. For example Bitshares which uses a Delegated Proof of Stake consensus algorithm. I believe they reached over 100,000 transactions per second during a test at some point. But as for the more common Proof of Work cryptos like Ethereum and Bitcoin, they are still far from reaching the speeds of the traditional systems. This is just the downside of having a much more secure, decentralized solution. But hopefully the Raiden Network takes Ethereum to the next level.
