#### :family\_mwgg: Strategy: Increase beacon chain peer count

{% hint style="info" %}
This change will result in increased bandwidth and memory usage. Tweak and tailor appropriately for your hardware.

*Kudos to* [*Rémy Roy*](https://www.reddit.com/user/remyroy/) *for this strat.*
{% endhint %}

Edit your `beacon-chain.service` unit file (except for Teku).

```bash
sudo nano /etc/systemd/system/beacon-chain.service
```

Add the following flag to increase peers on the `ExecStart` line.

{% tabs %}
{% tab title="Lighthouse" %}

```bash
--target-peers 100
# Example
# lighthouse bn --target-peers 100 --staking --metrics --network mainnet
```

{% endtab %}

{% tab title="Nimbus" %}

```bash
--max-peers=100
# Example
# /usr/bin/nimbus_beacon_node --network=mainnet --max-peers=100
```

{% endtab %}

{% tab title="Teku" %}

```bash
# Edit teku.yaml
sudo nano /etc/teku/teku.yaml

# add the following line to teku.yaml and save the file
p2p-peer-upper-bound: 100
```

{% endtab %}

{% tab title="Prysm" %}

```bash
--p2p-max-peers=100
# Example
# prysm.sh beacon-chain --mainnet --p2p-max-peers=100 --http-web3provider=http://127.0.0.1:8545 --accept-terms-of-use 
```

{% endtab %}

{% tab title="Lodestar" %}

```bash
--network.maxPeers 100
# Example
# ./lodestar beacon --network.maxPeers 100 --network mainnet
```

{% endtab %}
{% endtabs %}

Reload the updated unit file and restart the beacon-chain process to complete this change.

```bash
sudo systemctl daemon-reload
sudo systemctl restart beacon-chain
```

#### :gear: Strategy: Perform updates or reboots during the longest attestation gap
