寻求易用的多语言脚本基准测试工具（替代time且支持可视化）

Great question! The Computer Language Benchmarks Game is a solid resource for comparing mainstream languages, but it makes total sense to want a flexible tool to test niche options like Perl 6 on your own. Here are my top picks that replace the basic time command, with options for visualization:

Hyperfine #

• My go-to tool for this kind of work—way more powerful than the default time command, built specifically for benchmarking.
• Key features: Automatically runs commands multiple times to calculate average execution time and standard deviation, supports warm-up runs to eliminate cold-start bias, and can generate beautiful visual reports.
• Quick example usage:

  hyperfine --warmup 3 "perl6 your-script.p6" "python3 your-script.py" "ruby your-script.rb"
  

• Visualization: Add --export-html benchmark-results.html to generate an interactive HTML report with comparison charts, or --export-markdown results.md for a markdown-friendly summary with embedded charts. It works seamlessly with any language that runs via command line, including Perl 6.

BenchmarkDotNet #

• While it’s primarily known for .NET benchmarks, it supports running external command-line programs—perfect for testing scripts in any language.
• Key features: Enforces rigorous benchmarking practices (like handling JIT compilation and garbage collection where relevant), and generates detailed statistical reports along with SVG/PNG visualizations.
• To use it for multi-language tests, you’ll just need a simple C# config that calls your script commands as external processes—super straightforward to set up.

scc-bench #

• A lightweight CLI tool focused on fast, simple comparisons. It outputs results in JSON format, which makes it easy to build your own custom visualizations with tools like Python’s Matplotlib or even a basic web page.
• Example usage:

  scc-bench run -c "perl6 your-script.p6" -c "lua your-script.lua"
  

• Export the JSON results, then plug them into your preferred visualization tool to create charts tailored to your needs.

DIY Shell Script (For Quick, No-Install Needs) #

• If you don’t want to add new tools, you can whip up a simple shell script to handle repeated runs and calculate averages:

  #!/bin/bash
  # Define the commands you want to test
  commands=("perl6 your-script.p6" "python3 your-script.py")
  num_runs=5
  
  for cmd in "${commands[@]}"; do
      echo "=== Testing: $cmd ==="
      total_time=0
      for ((i=1; i<=num_runs; i++)); do
          start_time=$(date +%s%N)
          # Run the command and discard output (adjust if you need to capture it)
          $cmd > /dev/null 2>&1
          end_time=$(date +%s%N)
          # Convert nanoseconds to milliseconds
          run_time=$(( (end_time - start_time) / 1000000 ))
          echo "Run $i: $run_time ms"
          total_time=$((total_time + run_time))
      done
      avg_time=$((total_time / num_runs))
      echo "Average time: $avg_time ms"
      echo ""
  done
  

• To add visualization, just modify the script to output results to a CSV file, then use Excel or Google Sheets to create comparison charts.
