Performance Metrics

Performance is made up of both speed and deliverability. The metrics that measure these aspect include -


Time to First Byte (TTFB): Time to First Byte represents the duration between the moment a browser sends a request for a page and the instance it receives the first byte of data from the server. This duration is the time taken to establish a connection through TCP and SSL handshake (in cases where the request is made via HTTPS), along with the initial DNS lookup process.

First Contentful Paint (FCP): FCP signifies the moment when the browser initially renders the initial fragment of content from the Document Object Model (DOM), indicating to the user that the page is loading.

Time to Interact: Time to Interact denotes the duration required before visitors can commence scrolling on a page, clicking on links, and engaging with the website's interactive elements.

DOMContentLoaded: The DOMContentLoaded event triggers when the initial HTML document has been fully loaded and parsed. It is often utilised to ascertain when the page has concluded loading entirely.

Notably, certain files may be categorized as 'trailing resources,' signifying that they tend to load towards the end of the page loading process.

Examples of such trailing resources are analytics scripts (e.g., Google Analytics), which do not directly influence the user's site experience but are nonetheless part of the site's content.

In some instances, when the remainder of the site exhibits sluggish loading or includes incompatible resources, the functionality of these trailing resources may be adversely affected since the site fails to render them within a reasonable timeframe.


Number of Requests: It's pivotal to compare the total number of requests served from the 'original' website in China versus the 'post-Chinafy' website in China.

Typically, this comparison illustrates why the 'total page time' loaded may surpass the original, as the post-Chinafy site delivers a substantially higher volume of resources, ranging from 50% to 90% more.
