There was a problem hiding this comment.
The "at lodestar side" might be confusing, are we precomputing the next epoch transition somewhere else (not in lodestar)?
Looking at the code the two major tasks we do are
- precompute next epoch transition
- and prepare execution payload
Might be missing something

There's also the prepareExecutionPayload call that's not included in this timer.

But isn't that a different task or maybe I misunderstand what is meant by precomputeEpochTransition, my assumption is this includes epoch transition + hashing the state.
From my understanding the "at lodestar side" is redundant and can be removed as the task precomputeNextEpochTransition is only executed by Lodestar.
prepareExecutionPayload is part of preparing for next slot but not part of precomputing the epoch transition.
