Ethereum RPC Benchmark

This Node.js application allows you to run a steady state RPS (Requests Per Second) test against an Ethereum RPC endpoint for the eth_blockNumber method. It measures the average response time in milliseconds and provides insights into the actual RPS achieved.

Prerequisites

  • Node.js (version 14 or later recommended)
  • npm (comes with Node.js)

Installation

  1. Clone this repository or download the source code.

  2. Navigate to the project directory in your terminal.

  3. Install the required dependencies:

    npm install

Configuration

Before running the benchmark, you need to update some parameters in the index.js file:

  1. rpcEndpoint: Replace "https://your-rpc-endpoint-here.com/rpc" with your actual Ethereum RPC endpoint URL.
  2. targetRPS: Set this to your desired Requests Per Second. Default is 100.
  3. duration: Set the number of seconds you want the benchmark to run. Default is 10 seconds.
  4. method: This is set to "eth_blockNumber" by default. You can change it to test other RPC methods if needed.

Example:

const rpcEndpoint = "https://your-rpc-endpoint-here.com/rpc";
const method = "eth_blockNumber";
const targetRPS = 50;
const duration = 30;

Usage

To run the benchmark:

  1. Make sure you've updated the configuration parameters as described above.

  2. In your terminal, navigate to the project directory.

  3. Run the following command:

    npm start

  4. The benchmark will run for the specified duration and then display the results, including:

    • Average response time in milliseconds
    • Total number of requests sent
    • Actual RPS achieved

Customizing the Test

  • To test different RPC methods, update the method constant in index.js.
  • To adjust the load, modify the targetRPS constant.
  • For longer or shorter test runs, change the duration constant.

Important Notes

  • Ensure you have permission to perform high-volume requests on the RPC endpoint you're testing.
  • Be aware of any rate limiting on the RPC endpoint, as it may affect your test results.
  • For accurate results, run the test from a machine and network that can handle the desired RPS without bottlenecks.

Troubleshooting

If you encounter any issues:

  • Ensure all dependencies are correctly installed.
  • Check that your Node.js version is up to date.
  • Verify that the RPC endpoint URL is correct and accessible.
