…ometbft#3018) (cometbft#3023) This PR is a slight optimization to save one allocation per packet. We have much more worthwhile performance improvements to pursue, just driveby noticed it as I was reading through the code. (Though I am surprised this did add up to 1 second in total -- 4% of the processing time) This re-uses the byte reader's allocation across all ReadMsg's. There is no concurrenct access possible under safe usage (also implied by the reader) This is the cause of the 1s time on the far right:  --- #### PR checklist - [x] Tests written/updated - covered by existing tests - [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 <hr>This is an automatic backport of pull request cometbft#3018 done by [Mergify](https://mergify.com). --------- Co-authored-by: Dev Ojha <ValarDragon@users.noreply.github.com> Co-authored-by: Anton Kaliaev <anton.kalyaev@gmail.com> (cherry picked from commit ad8f851)
