We have noticed that a page opened for the first time is loading longer (from 8s), than a second time (1-3s). If the same page is loaded on a different computer for the first time on that computer (so no local cache exist yet), the page is also loaded faster (1-3s). So my question: why is the first load of a page so long (from 8s)?
I have another question: how does full page cache in magento 2 work?
