Now I know why I inadvertently click on the "Track read posts" and "RSS feeds". The menu bar containing those two are slow to load. (see screenshot) I click on the "empty" space which is active behind.

Hello Federico

I understand. I still prefer to separate the two things, i.e. in this thread to limit myself to the changes you've done to the theme of moodle.org (starting from core Moodle 4.0) from the fundamental UX changes happened in Moodle 4.0.

My problem is, since I don't have Moodle 4.0 in any of my Moodle instances, I'm still with 3.9 (LTS), it is difficult for me to separate the two. Here is something you could look in to on moodle.org though.

Have you tested keyboard navigation? I am no UX expert, but I'm used to navigate web sites with a basic set of keys, Space, the arrow keys, PgUp/PgDn, Home/End, to be specific. You can compare how they behave on moodle.org to say https://bbc.com.

What I notice is: On any new page all those keys are dead. Once I click anywhere in the middle section of a page, they get the focus and Space, PgUp/PgDn start to work. But not necessarily Home/End. Certain pages react to Home/End, others don't.

There is one unfortunate coincidence with "clicking on the middle". For some reason the mouse rests over the "Track the posts" and "RSS" areas when I enter a new page. If I just click to activate keyboard focus, I inadvertently kick those functions. RSS is not too bad, have to close the browser tab. But the other one upsets my read/unread taggings of forum posts.

Hallo Alexander

Wie gesagt, das Feld 'username' in der Tabelle 'mdl_users' ist der Schlüssel.

Achtung: Das ist aus dem Gedächtnis. Die letzte solche Übung liegt eine Weile zurück!

Ich würde eine https://docs.moodle.org/de/Sicherung_der_Moodle-Installation testweise machen, sicherstellen, dass auch die https://docs.moodle.org/de/Wiederherstellung_der_Moodle-Site geht, eine Wartungsfenster bekannt geben, die Operation durchführen und eine vorher abgemachte Gruppe die Site testen lassen. Beim Nicht-Erfolg die Site wiederherstellen und die Erkenntnisse hier diskutieren.

Hi Brenden

Thanks for the response. Yes, I know that you are busy in this field.


To you points:
> 1) If you are still thinking in terms of a big box or a little box then you are asking the wrong questions.
I get your point. If the Moodle instances are packages one per "box", it'll never be energy-efficient. Because the "box" is decided on the _peak_ load (at best), at normal load it is still burning the same power.

> 2) Roughly speaking if it is cheaper then it consumes less power.
> 3) Make this a business problem not a technical one.
Agree. A (Moodle) hosting business, i.e. running many Moodle instances, will automatically utilize the unused power of some customers to feed the others. As you say, they have the know how, and above all, have the interest not to waste hardware thereby automatically conserving energy. I can't deny that. In fact, I imagine Moodle Cloud to be a strong example of this effect. Imagine, every Moodle Cloud customer running his own box. Then Moodle will challenge the crypto miners in global warming.


But still there is a large segment of Moodle servers running in DIY mode. My OP is addressed to them. As many discussions in this forum would show, and discussions I'm having outside the forums, many institutions starting Moodle have exaggerated ideas of their usage. The irony is, for many institutions (in the West) the energy (and infrastructure) bill is still very small compared to the salaries. So they go for the "best server you can buy". The intention of the OP is to show them what modest and small boxes can do, as an argument against this kind of thinking.

"Concurrent users" is a vague term. If you have up to 2000 impatient students waiting for the bell to open an on-line exam, that'll be huge. On the other hand, if you expect up to 2000 "Online users (last 5 min)" as shown in the block Online users, then yours is still very big, but not that impossible like the 2000 exam candidates trying to enter the exam hall at same instant.

Please read the forum documentation: https://docs.moodle.org/en/Performance and https://docs.moodle.org/en/Performance_FAQ and many similar discussions in this forum.

Oops, I see, we're still in the General help forum. Please send a not to the moderator to move this discussion to Hardware and performance.

All that said, did you follow up Howard's hint: https://moodle.org/mod/forum/discuss.php?d=438788#p1766223.
