Is arbitrum faster than Ethereum?

Could you please elaborate on the question, "Is Arbitrum faster than Ethereum?" I'm curious to know how the two platforms compare in terms of transaction speed. Is Arbitrum's architecture designed to handle transactions more efficiently? What are the key factors that contribute to its potential speed advantage, if any? Additionally, how does Ethereum's scalability and speed compare to Arbitrum, given its widespread usage and the growing demand for faster and cheaper transactions in the crypto space? I'm interested in understanding the nuances of both platforms and how they stack up against each other in terms of performance.
