Why is Polygon faster than Ethereum?

Could you elaborate on why Polygon outperforms Ethereum in terms of speed? I'm particularly interested in understanding the technological advancements or architectural differences that contribute to this advantage. It seems Polygon has managed to achieve remarkable transaction speeds, and I'm keen to know the reasons behind this. Is it due to its innovative use of sidechains and multi-chain structure? Or perhaps there are other factors at play that make Polygon stand out in this regard. I'm also curious to know if this speed advantage translates into better scalability and usability for real-world applications. Your insights would be greatly appreciated.
