Methodology

Origin TTFB measures the server response time after bypassing CDN/cache layers. We set WooCommerce cart session cookies (woocommerce_items_in_cart, woocommerce_cart_hash, wp_woocommerce_session_*) to force cache-busting requests that reach the origin server.

This reveals actual server performance rather than cached response times, making it useful for identifying hosting and optimization issues. Sites with edge caching (Cloudflare, LiteSpeed, etc.) will show much lower homepage TTFB but similar origin TTFB to uncached sites on the same hosting.

For reference: Average homepage TTFB (cached) is 856ms, average cart page TTFB is 1305ms.
