Describe the bug

The Beacon HTTP API takes always > 2 sec to complete any request even for endpoint that don't require any processing.

We must investigate what is causing this delay:

  • Node to busy?
  • Some logic bug?
  • Fastify?
  • NodeJS itself?

Expected behavior

Respond to API requests in < 100ms times

Steps to Reproduce

Run lodestar beacon

time curl localhost:9596/eth/v1/beacon/headers/head

the state transition takes 1s-2s depending on the node so at least it'll take that amount of time for the node to finish the api when that happens

Non actionable issue directly. We are working on reducing main thread load an watching REST times closely
