<!-- Methodology -->
<div class="info-box">
<h3>📐 Methodology</h3>
<p>Each benchmark follows a consistent protocol:</p>
<ul>
<li><strong>Dataset</strong>: 100,000 elements, deterministic generation</li>
<li><strong>Warm-up</strong>: 5 untimed iterations</li>
<li><strong>Measured</strong>: 50 timed iterations, mean reported</li>
<li><strong>tsb runtime</strong>: Bun (latest)</li>
<li><strong>pandas runtime</strong>: CPython + pandas (latest)</li>
<li><strong>Ratio</strong>: tsb_time / pandas_time — below 1.0 means tsb is faster</li>
</ul>
</div>

<div class="info-box">
<h3>🤖 About</h3>
<p>
These benchmarks are generated automatically by the Autoloop
<code>perf-comparison</code> program. Each iteration adds a new function
comparison. Results are updated on every accepted iteration and deployed
to this page.
