libp2p-test-plans/perf

libp2p performance benchmarking

This project includes the following components:

• terraform/: a Terraform scripts to provision infrastructure
• impl/: implementations of the libp2p perf protocol running on top of e.g. go-libp2p, rust-libp2p or Go's std-library https stack
• runner/: a set of scripts building and running the above implementations on the above infrastructure, reporting the results in benchmark-results.json

Benchmark results can be visualized with https://observablehq.com/@mxinden-workspace/libp2p-performance-dashboard.

Provision infrastructure

Bootstrap

1. Save your public SSH key as the file ./terraform/modules/short_lived/files/perf.pub; or generate a new key pair with make ssh-keygen and add it to your SSH agent with make ssh-add.
2. cd terraform/configs/local
3. terraform init
4. terraform apply
5. CLIENT_IP=$(terraform output -raw client_ip)
6. SERVER_IP=$(terraform output -raw server_ip)

Build and run implementations

WARNING: Running the perf tests might take a while.

1. cd runner
2. npm ci
3. npm run start -- --client-public-ip $CLIENT_IP --server-public-ip $SERVER_IP

Deprovision infrastructure

1. cd terraform/configs/local
2. terraform destroy

Adding a new implementation

1. Add implementation to impl/.

• Create a folder impl/<your-implementation-name>/<your-implementation-version>.
• In that folder include a Makefile that builds an executable and stores it next to the Makefile under the name perf.
• Requirements for the executable:
  • Running as a libp2p-perf server
    • Command line flags
      • --run-server
  • Running as a libp2p-perf client
    • Input via command line
      • --server-ip-address
      • --transport (see runner/versions.ts for possible variants)
      • --upload-bytes number of bytes to upload per stream.
      • --download-bytes number of bytes to download per stream.
    • Output
      • Logging MUST go to stderr.
      • Measurement output is printed to stdout as JSON in the form of:

        {"connectionEstablishedSeconds":0.246442851,"uploadSeconds":0.000002077,"downloadSeconds":0.060712241}
        

2. In impl/Makefile include your implementation in the all target.
3. Reference implementation in runner/src/versions.ts.
