Polygon is targeting ~7.5-10M avg block gas usage post-London HF

[zhongfu]

After the London HF block, validators will begin to target an average block gas usage of parent.gasLimit / elasticityMultiplier. elasticityMultiplier is set to 2, so the base fee will scale accordingly in order to achieve an average block gas usage of 1/2 of the gas limit.

I'm guessing this effect (of... effectively decreasing tx throughput by ~half) isn't actually intended, but that's what's actually happening now. If that's the case, it'll probably be a good idea to update the bor start.sh scripts to reflect a block gas limit that's 2x as high as the intended average block gas usage to maintain the pre-London HF average block gas usage and tell validators to update their configs

Kind of tangential to the topic, but miner.gasPrice refers to minimum effective tip instead of minimum gasPrice after the London HF (i.e. EIP-1559 txes must have priorityFee set to at least 30 gwei and legacy txes must have a gasPrice that's at least baseFee + 30 gwei), so it might be a good idea to update documentation to highlight this change
