Page generation time is not displayed

Unfortunately, I must admit that the page generation time is not displayed in the admin panel. It is very uncomfortable.
I am also not happy (due to the lack of clarity of information) with the transfer of the page generation time for each visitor to the general table. There you won’t find any visitor how long the page was generated. Please return this functionality back.

I have neither the time nor the desire to constantly fix something and look for what does not work well, no offense … I rolled back to the third version - the fourth turned out to be too unsuccessful (IMHO)
