Response time

Everybody loves fast websites

What is page response time

There is a lot of things to be done after someone hits a link to your website:

  1. DNS name resolution;
  2. SSL/TLS connect/handshake to your server;
  3. TCP connection to your server;
  4. negotiations specific to the particular protocol(s) involved;
  5. redirects (e.g. from http:// to https://);
  6. content generation on your server;
  7. content transfer from your server to the user.

So the response time is the time from a "hit" to TTFB (time to first byte) or TTLB (time to last byte) of the transferred content depending on the check's method and technology. In this context the transferred content is not the whole webpage with images and other external resources and content, but the entire html-page (html-file) only.

So what's the problem?

Everybody loves fast websites. Really.

As Phocuswright research authority reports:

  • 57% of online consumers will abandon a site after waiting 3 seconds for a page to load;
  • 8 out of 10 people will not return to a site after a disappointing experience;
  • of these, 3 will go on to tell others about their experience.
  • There are also 2 great articles by Jakob Nielsen on this topic:

  • Website Response Times
  • Response Times: The 3 Important Limits
