Reducing Network Bandwidth Usage

Hosting your own execution client can consume hundreds of gigabytes of data per day. Because data plans can be limited or costly, you might desire to slow down data usage but still maintain good connectivity to the network.

Edit your execution.service unit file.

sudo nano /etc/systemd/system/execution.service

Add the following flag to limit the number of peers on the ExecStart line.

Geth

--maxpeers 10

# Example
# ExecStart=/usr/local/bin/geth --maxpeers 10

Besu

--max-peers 10

# Example
# ExecStart=/usr/local/bin/besu/bin/besu --max-peers 10

Nethermind

--Network.MaxActivePeers 10

# Example
# ExecStart=/usr/local/bin/nethermind/Nethermind.Runner --Network.MaxActivePeers 10

Erigon

--maxpeers 10

# Example
# ExecStart=/usr/local/bin/erigon --maxpeers 10

Reth

--max-outbound-peers 15 --max-inbound-peers 10

# Example
# ExecStart=/usr/local/bin/reth node --max-outbound-peers 15 --max-inbound-peers 10

Finally, reload the new unit file and restart the execution client.

sudo systemctl daemon-reload
sudo systemctl restart execution
