I've not encountered gtmatrix.com.

Is your site slow? I mean, do you and your users find it slow - which is all that really matters?

Hi,
Yes, It's really slow.
It's taking more than 10 seconds to load a public category page (without login needed).

To be honest, your site is going pretty well. I'm connecting from Italy.

Seems ok to me... but that's quite a theme. What's it doing when it's showing that "loading" animation for a couple of seconds. That's not Moodle.

That tool you are using ... did you purchase usage or did you look at their freebie?   If you looked at your site via freebie the location of the scanner was from Canada ... and browser emulation was Chrome.

How many hops away to that scanner is your server?

I'm using the free test, it has a paid option.
Don't think the scanner location is the point, I tried other free services and gave, almost, the same evaluation, include: PageSpeed and WebPageTest.

Optimising Moodle performance is complex and specialist. It can depend heavily on what activities users are using, caching, and importantly the hardware setup. So on one site adding more RAM can improve performance, but on an another it might not help. Caching is very important in configuration. As Howard says, is your site slow. What parts are slow and what parts of slow matter to you.

Mainly, rendering the pages is the most concerning issue.

The server is 32 GB RAM, and 10 CPU Cores. 

OS is Debian 10 with apache 2.4 (mpm_event) + mariaDB + php7. 3 fpm. 

For caching, I'm using redis cache on the same machine.

Is your file storage on the same machine?

Have you checked Redis is working? You get monitoring tools that show that it's actually storing stuff.

Is Apache and MariaDB configured to use the available RAM (by default, Apache tends to use too much and MariaDB too little)

Yes, Redis server is working and storing data.
According to the Apache and MariaDB, they are configured according to the Moodle performance recommendation in the Docs.

Scanning tools are suggesting loading the JS files with defer or async flag.
They claim this might save decent blocking time!
How harmful might be to experiment this suggestion?

Did you solve your previous problem: Viewing the log of a user or an activity is consuming the CPU and hanging the server! They seem to be related.

That could be the cause of the poor performance you observed above. I would follow up it further and get it solved first - you have received lot of pointers there.
