In the web scenarios, Quanta displays the “server time” of your site (time taken to generate and receive the HTML code).
According to our experience, the average on the Magento sites is 400ms. Our recommendations for the server time is 100ms.
We consider that beyond 450ms, the answers time are too slow. Beyond 1s the situation is worrying because your conversion rate is suffering.
To give you an example of how important this is, ETAM reduced their load time by 700ms and increased their conversion rate by 20%!
