Chain/Network: Gnosis

Expected behaviour

Reasonable attestation performance. I have an Ethereum geth/lighthouse node on the same hardware/connection that gets 98% attestation inclusion effectiveness.

Actual behaviour

Currently 87% attestation inclusion effectiveness (and dipped below 80% earlier today).

Missed attestations, no specific reason in logs. There are some reorgs but it's not always the reason.

Some interesting analysis:

• All missed attestations are from Nethermind nodes.
• Top 100 validators are ALL Nethermind nodes (see Block Extra Data). Yes I checked them all https://gnosischa.in/validators/leaderboard

Steps to reproduce the behaviour

Run a validator on the Gnosis network.

Even for ETH, Erigon always have had poor attestation inclusion. Nethermind is way more reliable with 1 or 2 missed attestations every month.
