Nice Bench

This Python script benchmarks how different nice levels affect CPU-bound tasks, measuring throughput and latency. It runs processes with varying nice levels to observe their impact on execution time.

Requirements

• Python 3.x
• A Unix-like OS with nice support (e.g., Linux, macOS)

Usage

Command-line arguments:

1. -t, --task-size: Sets the task size as a power of 10 (default: 9).
2. -n, --nice-duplicates: Number of processes per nice level (default: 2).

Example Usage

Default run:

sudo python3 nice-bench.py

Custom run without duplicate processes and reduced task size:

sudo python3 nice-bench.py -t 7 -n 1

Note: Invocation with sudo is required to set nice level for restricted nice levels.
