## What it is
Benchee is an easy-to-use and extensible microbenchmarking library for Elixir. It runs functions with warmup, measures run time and memory consumption, and reports rich statistics with plugin support for HTML reports and graphs.

## Use cases
- benchmark elixir functions
- compare performance of two code implementations
- measure memory usage of elixir code
- generate html benchmark reports with graphs
- run microbenchmarks with warmup and statistics
- profile average and deviation of function runtimes

## When to choose
- you need to compare the speed or memory usage of different Elixir implementations
- you want statistical benchmark results like ips, median, and percentiles
- you want an extensible benchmarking tool with plugins for graphs and exports

## When to avoid
- you need profiling of a whole application rather than microbenchmarks
- you are not working in Elixir or on the BEAM
- you need continuous production performance monitoring rather than local benchmarking

## Facets
- artifact type: library
- maturity: stable
- function: benchmarking, developer-tools
- domain: developer-tools, performance, testing
- platform: elixir, jvm, windows
- tags: microbenchmarks, statistics, elixir, graphs, extensible, erlang, linux, macos
