Crank is the benchmarking infrastructure used by the .NET team to run benchmarks including (but not limited to) scenarios from the TechEmpower Web Framework Benchmarks.
One of the goals of this system is to give developers a tool that lets them work on performance and measure potential improvements very easily. Some of the capabilities are:
- Deploy and benchmark multi-tiered applications based on .NET or Docker containers
- Store results in JSON or in SQL Server for charting
- Customize the applications or their environment to test different settings
- Collect traces

The benchmarking infrastructure is made of these components:
- crank-agent - A service that executes jobs that run as part of a benchmark
- crank - A command line utility that can enqueue jobs and record results
There are also some built in jobs:
- wrk - An http client benchmarking tool. This tool is used when benchmarking TechEmpower https://github.com/wg/wrk (Linux only).
- wrk2 - An http client benchmarking tool optimized for latency testing https://github.com/giltene/wrk2 (Linux only).
- bombardier - A go based http client benchmarking tool https://github.com/codesenberg/bombardier (cross-platform).
- Read the documentation
- Install the crank controller dotnet tool:
dotnet tool update Microsoft.Crank.Controller --version "0.2.0-*" --global - Use some predefined scenarios
