The documentation and past discussions were not meant to be digested in one chunk, rather to list the (too) many possibilities. Maybe you recognize something.
 
If it not the case, you have to discover a "consistency" and follow up. The one you have is the participants page of a course. If you have only a small number of participants and they are locally (Moodle internal) authenticated, there is no reason other than the server not yielding. Honestly, I don't know how to calculate the IOPS given the number of participants. But if that exceeds the IOPS allowed by the hosting, then it is clear case. Ask for a report of IOPS from the hosting provide and see whether it shows any correlation of your operation and the IOPS hitting the cap. That is the only specific hint I have right now.
 
BTW, if the participants page is consistently slow, then it is not "intermittent".

Generally, Performance and Performance FAQ are compulsory reading on this topic.

In the case of your hosting, it is not a "VM" in the sense of a VPS, rather a shared hosting service. So there is a factor which could effect your performance but invisible to you: That is what the other customers doing on the server. If the server is overbooked you may see these random drops in performance.

Although the Moodle Benchmark result is not great, if could well be enough for a dozen or more users working at the same time.

That IOPS warning is a killer. If your site consumes more resources than the hosting provider allows, obviously you can't run Moodle there!

If you ask the AI bot behind Təhsil Portalı, you'll get even faster response: https://moodle.org/mod/forum/discuss.php?d=462414#p1857720 འཛུམ་དྲག་

Or you can tread a slower but presumably more goal-oriented path by starting at the compulsory reading, Performance and Performance FAQ, supported by the many, many discussions in this forum.

Yeah, Təhsil Portalı (Education Portal in Azerbeijani) is not the only AI bot on moodle.org. There is a certain style in those "didascalia" which rings bells in the back of my mind - and it tires. Can't describe what that "style" is, I'm not a linguist, I always think of the last sentences from a radio when the batteries start dying, something lacklustre - as with anything artificial, when I think of it. There must be automated checks to find out. Maybe one could ask another AI bot; Is there something called an AI traitor?

Now seriously, do we really want to feed, "educate", our children this regurgitation?
