## Issue Addressed
Reduces the effect of late blocks on overall node buildup
## Proposed Changes
change the capacity of the channels used to send work for reprocessing in the beacon processor, and to send back to the main processor task, to be 75% of the capacity of the channel for receiving new events
## Additional Info
The issues we've seen suggest we should still evaluate node performance under stress, with late blocks being a big factor.
Other changes that could help:
1. right now we have a cap for queued attestations for reprocessing that applies to the sum of aggregated and unaggregated attestations. We could consider adding a separate cap that favors aggregated ones.
2. solving #2848
