## Health v2 (maintenance only)
Score: 77/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 100, release rhythm 35, longevity 100
- inputs: {"age_days": 2325, "days_push": 0, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Crank is Microsoft's benchmarking infrastructure used by the .NET team to run performance benchmarks, including TechEmpower web framework scenarios. It consists of a CLI controller that enqueues benchmark jobs and an agent service that executes them, with support for multi-tiered .NET or Docker-based applications.

## Use cases
- benchmark http server throughput and latency
- run techempower-style web framework benchmarks
- measure performance improvements of my application
- load test an api endpoint with wrk or bombardier
- collect performance traces during benchmarks
- benchmark multi-tier dockerized applications

## When to choose
- you need reproducible, automated HTTP benchmarking of web servers or APIs
- you want to compare performance across application configurations or frameworks
- you need to run TechEmpower-style scenarios with result storage and charting

## When to avoid
- you only need a quick one-off load test without infrastructure setup
- you need browser-based or client-side performance profiling
- you want simple GUI-driven benchmarking

## Facets
