Hi and welcome to devnet,

@wrekler said in HTTPS POST performance:

How relevant is knowing the server?

It is relevant because:

It might be sleeping if for example it's an heroku free tier that hasn't been used for some times. Therefore the first query will have to wait for the server to awaken thus it will be longer. It might require authentication which takes some time on first query to setup and allow to process. It might need to query some slow to start resource to answer your question etc.

Oh, I see. Well it is not a my server, it is a thirdy party server, so I can't answer to all that question. All I know is:

It is hosted on akamai.com Acqtually it require some authentication data that I give with POST data

So I think I can't optimize requests server side, all can I do is caching DNS/TCP/SSL requests but I don't know if Qt 5.11.2 actually implements all that suggestions

Hi,

Since it's username/password your original clientGUI::provideAuthenication should have worked however I would not have read the content of the reply just called setUser and setPassword
