I notice that the page loads are much slower when I log in as a user (admin or woocommerce client).
Logged in users get also cached pages and the speed is the same, but the cache for logged in users is private. That means that every logged in user has his own private cache.
Thank you… But precisely, the speed is not the same depending on whether the user is logged in or not (the pages load instantly if the user is not logged in… but it takes longer when he is connected).
If a page isn’t cached it doesn’t matter if a user is logged in or not. The same with connection (What do you mean with connection?), but there may be difference if you have ESI enabled. Otherwise there is no difference. Login and request a URL twice and you will see no difference.
Sorry… I test again and it’s ok now…
