I'm not really sure about these benchmark results. Will rerun on another machine to verify. |

Here are some more stable results. It looks like the effect of this change is very minimal: |

This should be ready now. The package rlp change has moved to #27987 |
Since the first three fields of Log are the ones that should appear in the canon encoding, we can simply ignore the remaining fields via struct tag. Doing this removes an indirection through the rlpLog type.
If kind == rlp.Byte, the size reported by Stream.Kind will be zero, but we need a buffer of size 1 for ReadBytes. Since typed txs always have to be longer than 1 byte, we can just return an error for kind == rlp.Byte.

…thereum#27976) Just some minor optimizations I figured out a while ago. By using ReadBytes instead of Bytes on the rlp stream, we can save the allocation of a temporary buffer for the typed tx payload. If kind == rlp.Byte, the size reported by Stream.Kind will be zero, but we need a buffer of size 1 for ReadBytes. Since typed txs always have to be longer than 1 byte, we can just return an error for kind == rlp.Byte. There is a also a small change for Log: since the first three fields of Log are the ones that should appear in the canon encoding, we can simply ignore the remaining fields via struct tag.

core/types: transaction and receipt encoding/decoding optimizations Conflicts: core/types/transaction.go conflict due to us adding a parameter to decodeTyped function. Added both changes.
