To quickly clear the network data:

rm -rf Node-1/data/DATABASE_METADATA.json && rm -rf Node-1/data/caches/ && rm -rf Node-1/data/database/
rm -rf Node-2/data/DATABASE_METADATA.json && rm -rf Node-2/data/caches/ && rm -rf Node-2/data/database/
rm -rf Node-3/data/DATABASE_METADATA.json && rm -rf Node-3/data/caches/ && rm -rf Node-3/data/database/
rm -rf Node-4/data/DATABASE_METADATA.json && rm -rf Node-4/data/caches/ && rm -rf Node-4/data/database/



Command to run Caliper:

npx caliper bind --caliper-bind-sut besu:latest

npx caliper launch manager \
    --caliper-benchconfig benchmarks/scenario/ERC-20/config.yaml \
    --caliper-networkconfig networks/besu/QBFT-Network/ERC20NetworkConfig.json \
    --caliper-flow-skip-install \
    --caliper-workspace .


Setting up a Gas Free Network (Recommended Settings): 

“To avoid the limitation of gas consumption in smart contract deployment and transaction execution, we configured all Besu blockchain networks to be gas-free by setting “gasLimit” to the maximum “0x1fffffffffffff”, “contractSizeLimit” to the maximum 2147483647, and the node startup option “min-gas-price” to 0. Also, we set the difficulty to the minimum “0x1” and the transaction pool queue size to the default 4096.”

Running Async Profiler for more information about Besu:

#!/bin/bash
# Start the Besu node
besu --data-path=Node-1/data --genesis-file=genesis.json --rpc-http-enabled --rpc-ws-enabled=true --rpc-ws-port=8546 --rpc-ws-host=0.0.0.0 --p2p-host=51.15.132.70 --rpc-http-host=0.0.0.0 --rpc-http-api=E>

# Get the PID of the Besu process
BESU_PID=$!

# Start async-profiler
async-profiler/profiler.sh -d 120 -f async-profiler/output.html $BESU_PID
