Why is Avalanche faster than Ethereum?

Could you elaborate on why Avalanche outperforms Ethereum in terms of speed? I'm genuinely interested in understanding the technical differences that contribute to this advantage. Avalanche, as I understand, utilizes a unique consensus mechanism known as the Avalanche consensus, which seems to facilitate rapid transaction confirmations. On the other hand, Ethereum relies on the Proof of Work consensus algorithm, which often leads to longer confirmation times. Could you further explain how these consensus mechanisms differ and how they impact the overall speed and efficiency of these blockchain platforms? Additionally, are there any other factors, such as architecture or scalability, that contribute to Avalanche's superior performance? Thank you for your insights.
