WooCommerce Speed Test

Test your store's real performance on uncached checkout pages - where speed actually affects your sales

Enter Your Store URL

We test 3 pages: Homepage (can be cached if configured), Cart and Checkout (always uncached - WooCommerce session cookies bypass any cache)

Recommended

General Test

Quick single-request test to measure your server's baseline performance.

  • Homepage (cacheable)
  • Cart page (bypasses cache)
  • Checkout page (bypasses cache)
  • Screenshots of each page

Concurrent Test

Stress test with 50 simultaneous requests to see how your server handles real traffic.

  • Everything in General Test
  • 50 requests to checkout
  • 10 concurrent connections
  • Shows min/avg/max TTFB

What is TTFB and Why It Matters

Time to First Byte is the single most important metric for WooCommerce server performance

Request
Server Processing
First Byte
Browser sends request
PHP + Database work
Response starts

TTFB = Server Speed

TTFB measures how fast your server processes requests. It includes:

  • PHP execution time
  • Database queries
  • WordPress/WooCommerce processing
  • Plugin overhead

Unlike page load time, TTFB cannot be improved by frontend optimization, CDN, or caching on dynamic pages.

Why We Test Uncached Pages

Most speed tests only show cached homepage performance - we show what your customers actually experience

Homepage (Cacheable)
Can be served from CDN/cache if configured. Shows caching speed or raw server speed if no cache.
Cart Page (Uncached)
WooCommerce session cookies bypass cache. This is your real server speed that customers experience.
Checkout (Uncached)
The most critical page. Slow checkout = abandoned carts. This is where you lose money.
Concurrent Test
50 simultaneous requests to checkout. Shows how your server handles real traffic load.

What's a Good TTFB?

For uncached WooCommerce pages (cart, checkout, my-account)

0ms 350ms 700ms 1000ms+
< 350ms

350-700ms
Acceptable - Room to improve
> 700ms
Slow - Losing sales
