what would you see if someone was running a live session from Ubuntu,Puppy or say Tails/pgp ect. ,,,what would it store?
It wouldn't matter what type of web browser or operating system a member is using soandso - they may see an error if they happened to hit post and that post hit the server at the very instant I clicked on save changes - the change is done probably in microseconds.
At the bottom of my Admin page after clicking on a particular thread this is typical of the response time and most of that is spent processing the php files to build the page to be sent.
64 ms is the time taken for the server to process the request from a user and deliver a response.
At the member/users end this will add to internet transit time (transit time is greater than the server response itself and the SSL encryption/security hand shaking adds to the delay).
An unsecured site will give the user faster page loads.
