Beautiful, powerful, and pythonic benchmarks engine for Python code.

Features:

• Follows best practices of benchmarking to produce the most reliable results.
• Detects caching and side-effects.
• Traces memory usage and allocations (opt-in).
• Opcodes tracing for reproducble benchmarks (opt-in).
• 100% type safe.
• Zero dependency.
• Highly configurable.
• Nice and colorful output.
• Ships with CLI to discover and run all benchmarks.
• A friendly API to write your own logic on top of benchmarks.

Installation

python3 -m pip install true-north

Usage

import true_north

group = true_north.Group()

@group.add
def math_sorted(r):
    val = [1, 2, 3] * 300
    # timer start before entering the loop
    # and stops when leaving it
    for _ in r:
        sorted(val)

# run and print all benchmarks in the group
if __name__ == '__main__':
    group.print()
