See the project board for the team's current priorities: https://github.com/orgs/cometbft/projects/1 --> Makes an internal buffer that we can re-use when building blocks. This seems to save on average 75 microseconds per block for osmosis blocks. (Ranging between 1-2 block parts in the relevant time range) This should be scaling roughly linear with block size. This lets us remove one allocation cost per complete block coming in. We only need to re-allocate on the next "biggest ever seen" block we see. --- - [x] Tests written/updated - [x] Changelog entry added in `.changelog` (we use [unclog](https://github.com/informalsystems/unclog) to manage our changelog) - [x] Updated relevant documentation (`docs/` or `spec/`) and code comments - [x] Title follows the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) spec (cherry picked from commit 16839d8)
