Micro benchmark workloads

A blockchain system comprises multiple layers, and each layer may have different impact on the overall performance. We provide several workloads to stress the layers in order to understand their individual performance.

Workloads

• Consensus layer - DoNothing This workload is integrated in the ycsbc-based driver in blockbench/src/macro/kvstore directory.

  To use this workload,

  # Hyperledger
  ./driver -db hyperledger -threads 1 -P workloads/workloada.spec -txrate 5 -endpoint localhost:7050/chaincode -wl donothing
  # Ehtereum
  ./driver -db ethereum -threads 1 -P workloads/workloada.spec -txrate 5 -endpoint localhost:8545 -wl donothing -wt 20
  # Parity
  ./driver -db parity -threads 1 -P workloads/workloada.spec -txrate 5 -endpoint localhost:8545 -wl donothing -wt 20

Node.js dependency libraries

• Use npm install to install the dependency libraries
• For all ethereum experiments, use start_ethereum.sh to start geth client first.
