Performance Tests

This directory contains all k6-based performance tests used to benchmark the Mojaloop switch under realistic, high-throughput conditions.

The tests are executed using the k6 Operator on a dedicated Kubernetes cluster and simulate full Mojaloop transaction flows across multiple DFSPs, including Discovery → Quotes → Transfers.

Test Model

  • Load Generator: k6 Operator (Kubernetes-native)
  • Execution Model: Constant Arrival Rate (target TPS)
  • Transaction Flow:
    1. Party Discovery (ALS)
    2. Quote request
    3. Transfer execution
  • DFSP Topology:
    • Multiple DFSP simulators acting as payers and payees
    • Weighted DFSP pairing supported
  • Metrics Captured:
    • End-to-end latency
    • Phase-wise latency (Discovery / Quotes / Transfers)
    • Success rate
    • Completed transactions
    • TPS achieved

Typical Workflow

  1. Prepare Infrastructure
    Ensure Mojaloop switch, DFSPs, and k6 infrastructure are running.
    See: ml-perf-whitepaper-ws/infrastructure/README.md

  2. Test Execution Execute the performance tests.
    See: ml-perf-whitepaper-ws/performance-tests/src/README.md

  3. Collect Results
    Review and record summaries, logs, and metrics under ml-perf-whitepaper-ws/performance-tests/results.
    See: ml-perf-whitepaper-ws/performance-tests/results/README.md

Notes

  • Test parameters are fully driven via Helm values and environment variables.
  • Multiple TPS scenarios (e.g. 500 / 1000 / 2000 TPS) can be executed using different values files.
  • The k6 cluster is isolated from the Mojaloop switch and DFSP clusters to ensure clean load generation.

This structure allows repeatable, scalable, and production-like performance testing of Mojaloop.
