The Solana protocol currently has a flat base fee irrespective of the compute used by the TX, but it charges a flat upfront bond per regular account creation that makes it 'rent-exempt'. The price arbitrage is causing these large multiples. That said, if blocks are full, users will have to pay relatively higher priorityFees compared to more lightweight TXs, given that those are prioritized based on (priorityFee/compute)
