Is it normal if checkout page takes around 17 - 20s to fully load until the loader image disappears and user can enter some data?
I am running magento 2.3-dev branch in production mode, all the cache is on, redis installed on the server. DOM is loaded under 1s, but then there are a lot of html files loaded by ajax and also many minified js. That's why I have to wait around 20 s.
I tried to compare some magento 2 shops and found this cache extension, but even on their shop the checkout page takes around 20s to fully load.
My question is, if this is what I can expect on our live server and if it's normal loading time? Is there something I can do about it?
