Answer 3

And at what stage do you have this delay?
Try testing the site first. For example, through this service
www.webpagetest.org
And post the test results here.
Then it will be possible to say in detail what exactly you should optimize.

Answer 4

You please inspect the site and with the record of the network, what time is eating?
In general, you need to optimize both the site and the server, and both can give improvements every 20 times, depending on the settings.
For example, you have php cache disabled
