Do you have a Large Moodle 4.5 site and it seems to be slow at waking up and returning results?

This is the kind of thing which I’m talking about which are noticeable in Devtools

5.56 seconds for the time to first byte on /my page !? What is it doing ?!

Well after lot of looking under the hood I can reveal that it is all to do with 2 settings in MySQL

After changing these from the default the site is back to performing as you’d expect, a response in 614 milliseconds.

Interested in knowing what these are, please reach out – otherwise I may just think that I’m talking to myself.
