Overview
Principle of systematic performance benchmarking across git commits with structured metrics collection, persistence, and visualization.
Description
Benchmark Orchestration is the practice of running reproducible performance tests across multiple code versions (git commits) to detect performance regressions. A complete benchmarking system requires: (1) an orchestrator that manages code version checkout and test execution, (2) a metrics recorder that captures device utilization and model performance data, (3) a persistence layer (database or files), and (4) a visualization layer for stakeholders to monitor trends. The v1 benchmark system in Transformers implements all four layers using optimum-benchmark for execution, PostgreSQL for storage, and Grafana for visualization.
Usage
Apply this principle when maintaining a performance-sensitive library where regressions must be detected between releases. Requires infrastructure for running benchmarks in a controlled environment (consistent hardware, isolated execution) and a mechanism for comparing results across code versions.
Theoretical Basis
The benchmarking pipeline follows a commit-traversal pattern:
For each commit to benchmark:
- Check out the target commit in an isolated environment
- Execute benchmark suite with controlled configuration
- Record metrics: latency, throughput, memory, device utilization
- Store results with full provenance (commit SHA, branch, timestamp)
Aggregation:
- Combine per-commit results into time-series data
- Compute statistical summaries (mean, std, percentiles)
- Detect regressions via threshold-based or statistical comparison
Pseudo-code:
# Abstract algorithm (NOT real implementation)
for commit in commits_to_benchmark:
checkout(commit)
install_package()
for model, config in benchmark_matrix:
metrics = run_benchmark(model, config)
store_metrics(commit, model, metrics)
results = aggregate_by_commit(all_metrics)
detect_regressions(results, threshold)
