Long saving time, how to debug

[lpa]

I have quite a quite large template having 57 fields. Now the saving of a page with that template takes over a minute on the production server. The server is a shared webhotel server with PHP 8.2. On my own vps server the saving takes under 3 seconds. 

Tracy shows in the timers  for the last save stage, the redirect to ?id=222&s=1&c=0, 1,2 seconds time. But the Execution time for this in System info is 1400 ms. 

Where can I see what causes the one minute delay? I can't find the point in Tracy panels to debug more.

There is a panel on tracy to see all the database queries executed, maybe something there?
