In theory, Ethereum's scaling plan let's it reach 1 million transactions per second: https://www.ccn.com/vitalik-buterin-ethereum-will-eventually-achieve-1-million-transactions-per-second/ https://www.ccn.com/vitalik-buterin-ethereum-will-eventually... How that works out in practice remains to be seen. Recent developments are encouraging for scalability. For example Roll Up is a plan to use zk-SNARKs to create very secure sidechains that would increase the total capacity of a single Ethereum chain to 17,000 tps or more. With sharding, where Ethereum operates 100 chains at once, that would mean Ethereum would be able to achieve 1.7 million transactions per second.
