Will Ethereum 2.0 be faster than Solana?

Could you please elaborate on the potential speed improvements that Ethereum 2.0 is expected to bring, and compare it to the current capabilities of Solana? Are there any specific metrics or benchmarks that can be used to objectively assess the difference in transaction speeds between the two networks? Additionally, what are the key factors that could influence the actual performance of Ethereum 2.0 once it's fully implemented, and how do these factors compare to those affecting Solana's speed?
