title: Ethereum - In regard to its TPS
body: <p>I want to use Ethereum as private chain in a network. But as it would inside a transactional system, performance required is good. Ethereum on the other hand is said to have 15 TPS</p>
  
  <p>What does 15 TPS mean ? That is not a practical performance if I try to use it for payment settlement in a private network</p>
  
  <p>There would be probably 5000 - 6000 transactions per second and later more</p>
  
  <p>How can I then use Ethereum for such a situation ?</p>
