Global Performance Benchmarking

Application speed is a competitive advantage. However, "Speed" is not a single number. It is a spectrum that changes based on where your user is located. Using supaguard’s Global Network, you can benchmark your real-world performance from multiple geographic hubs simultaneously.

Key Metrics to Benchmark

When running checks from different regions, pay attention to these Premium Emerald metrics:

1. TTFB (Time to First Byte)

The time it takes for the browser to receive the first byte of data from your server. High TTFB in one region usually indicates a CDN or routing issue.

2. LCP (Largest Contentful Paint)

Measures when the main content of the page has likely loaded. This is a critical metric for SEO and user perception.

3. Connection Latency

The raw time it takes for a network request to travel to your server and back.

How to BenchMark with supaguard

You can use Playwright's built-in performance.getEntriesByType to capture detailed timings during your synthetic check.

import { test, expect } from '@playwright/test';

test('benchmark page speed', async ({ page }) => {
  const start = Date.now();
  await page.goto('https://your-app.com', { waitUntil: 'load' });
  const end = Date.now();

  // 1. Capture basic load time
  console.log(`Page Load Time: ${end - start}ms`);

  // 2. Capture Web Vitals via Navigation Timing API
  const performanceTiming = await page.evaluate(() => JSON.stringify(window.performance.timing));
  const timing = JSON.parse(performanceTiming);
  
  const ttfb = timing.responseStart - timing.navigationStart;
  expect(ttfb).toBeLessThan(1000); // Fail if TTFB > 1s
});

Regional Variance: A Real-World Example

[!TIP] If you see high variance like the example above, consider optimizing your Edge Caching strategy or deploying regional API clusters.

Benchmarking vs. Uptime

• Uptime Monitoring: Tells you if the site is alive.
• Performance Benchmarking: Tells you if the site is usable.

supaguard allows you to set Performance Thresholds. If your LCP drops below a certain target in any region, we can trigger a Degraded Alert so your team can investigate before it becomes a critical outage.
