Describe the bug

Block proposing times are unstable causing missed proposed blocks

Prater:

Mainnet:

Expected behavior

Propose blocks strictly in under 3 seconds. Ideally in less than 1 second always

Todo

First we need to understand better what's slow about proposing a block

  • Add more histogram metrics on each step of proposing a block. See Lighthouse as a good example

Could be related to #4002

We need to time proper metrics for:

  • beacon node side strict block production times
  • publish block delay time
