Onebillionloops

A performance benchmarking tool that executes one billion loops to measure system performance using Elixir's concurrent capabilities.

This module implements a billion-loop benchmark using:

• Chunked processing (1M iterations per chunk)
• Concurrent execution using Task.async_stream
• Automatic detection of available CPU schedulers
• Tail-recursive implementation for memory efficiency

Run the benchmark in an IEx session:

# Start IEx with the project
iex -S mix

# The benchmark will automatically run and display timing results

• Total iterations: 1,000,000,000
• Chunk size: 1,000,000 (configurable)
• Concurrency: Matches available CPU schedulers
• Implementation: Tail-recursive countdown function

If available in Hex, the package can be installed by adding onebillionloops to your list of dependencies in mix.exs:

def deps do
  [
    {:onebillionloops, "~> 0.1.0"}
  ]
end
