.compare(qea_path, xmi_path) ⇒ Hash

Compare QEA and XMI parsing performance

Examples:

results = Lutaml::Qea::Benchmark.compare(
  "model.qea",
  "model.xmi"
)
puts "QEA: #{results[:qea][:time]}s"
puts "XMI: #{results[:xmi][:time]}s"
puts "Speedup: #{results[:speedup]}x"

Parameters:

  • qea_path (String) —

    Path to QEA file

  • xmi_path (String) —

    Path to XMI file

Returns:

  • (Hash) —

    Benchmark results

def compare(qea_path, xmi_path) # rubocop:disable Metrics/MethodLength
  qea_result = measure_qea(qea_path)
  xmi_result = measure_xmi(xmi_path)

  speedup = if qea_result[:time].positive?
              (xmi_result[:time] / qea_result[:time]).round(2)
            else
              0
            end

  {
    qea: qea_result,
    xmi: xmi_result,
    speedup: speedup,
    improvement_percent: ((speedup - 1) * 100).round(1),
  }
end

.format_results(results) ⇒ String

Format benchmark results for display

Parameters:

  • results (Hash) —

    Results from compare method

Returns:

  • (String) —

    Formatted text
