Performance analysis of ethereum transactions in private blockchain

Abstract

Ethereum, the well-known blockchain platform, does not have any limit for block size, unlike Bitcoin. However, there are other obstacles in processing unlimited transactions per second. Ethereum blockchain code runs by different clients, and they run on different speed and present the different level of performance. This paper studies Ethereum transactions and it analyzes two most popular Ethereum clients, Geth and Parity, on a private blockchain to obtain the better understanding of the effect of different clients on Ethereum performance. The results show that the transactions are 89.8 percent on average faster in Parity client in comparison with Geth client, using the same system configuration.
