What was always slow about it was the page rendering time by the browser

• because the JS that creates the navigation for N SQL queries is O(N*N) , also if you have a lot of HTML it gets a little more worse than O(N*N)

So maybe you have installed some extensions that increase the number of SQL queries
how many SQL queries do you have in the page that appears to be slow ?

Thank you for your quick response.

The admin panel was showing a slow execution even in com_content (e.g. showing articles)

I installed the ACL Manager extension (powered by Sander Potjer) and it showed than there were some orphan assets.

Once those orphan assets have been fixed, the Debug System has returned to work fine, I mean, with a suitable response time.

So, the problem may be related to those orphan assets...

Anyway, thank you so much for your help.
