Blockbench

BlockBench is an open-source benchmarking framework for private blockchain systems, with macro workloads for overall performance and micro workloads for individual system layers.

Understand the project

Practical overview

When it fits

Use BlockBench when a platform comparison or performance investigation needs repeatable workloads, and select a macro or micro benchmark according to whether the question concerns overall processing or a particular layer.

Who it is for

  • Developers comparing private blockchain platforms.
  • Researchers and engineers examining performance across blockchain system layers.

Documented uses

  • Compare overall performance using YCSB or SmallBank workloads.
  • Measure consensus behavior with DoNothing.
  • Evaluate read/write or analytical data-model workloads with IOHeavy or Analytics.
  • Examine execution-layer performance with CPUHeavy.
Before you choose

Requirements & limits

The repository is public and licensed under Apache-2.0.

  • The workload set spans key-value and OLTP macro benchmarks as well as consensus, data-model, analytics, and execution micro benchmarks.
  • Repository instructions cover Ethereum, Hyperledger Fabric 0.6, 1.4 and 2.2, Parity, and Quorum.
  • Dependencies include C++ libraries and Node.js packages; benchmark-specific blockchain software and SDKs are also listed.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Prepare BlockBench micro-workload dependencies

Install the Node.js dependency libraries used by BlockBench micro workloads.

Before you start

  • A Node.js environment with npm available.
  • Access to the BlockBench repository.

Steps

  1. Open the repository's src/micro directory.

  2. Run the command below there to install the dependency libraries.

    Documented command
    npm install

Expected outcome

The micro-workload dependency libraries listed by the project are installed.

Guide limitations

  • This covers dependency installation only; it does not describe configuring a blockchain system or running a benchmark.
  • The README does not specify Node.js or npm versions.

Prepare patched restclient-cpp for Parity benchmarks

Apply BlockBench's supplied patch to restclient-cpp before proceeding with its normal installation for Parity RPC processing.

Before you start

  • A restclient-cpp source directory.
  • The BlockBench repository, including benchmark/parity/patch_restclient.

Steps

  1. Go to the top-level directory of restclient-cpp.

  2. Apply the BlockBench patch with patch -p4 < $BLOCK_BENCH_HOME/benchmark/parity/patch_restclient.

  3. Proceed with the normal restclient-cpp installation.

Expected outcome

The patch adds an `Expect: ` header to POST requests, which the README says considerably improves RPC request processing speed at Parity.

Guide limitations

  • The README does not provide the normal installation procedure or a verification test.
  • This patch guidance is specific to the Parity setup.
