This is great, appreciate 
!
Some more input about the opcache settings:
- By using the settings as above, I investigated the opcache use by this php script: https://github.com/rlerdorf/opcache-status/blob/master/opcache.php
- In
/var/www/opcache.phpand/var/www/nextcloud/opcache.phpit shows now the correct adjusted different settings. But scripts from within nextcloud are now cached in both “instances”, lets say they block a certain amount of the 32 MB available cache size outside /nextcloud and also from the 128 MB available inside. - I am not sure how this is handled in that case, if opcache now blocks 32 MB + 128 MB or if inside /nextcloud the global 32 MB are just extended. The latter fits to what I see, as php files from within /nextcloud are visible on both opcache.php pages. Actually both pages show all files, the same free cache size, just different used+available cache size.
- As I see this now, >100 MB blocked cache size inside nextcloud folder looks too much for me, the additional cache here seems to be shown always as used. You see there is clarification needed here
.
- Btw: You can open /nextcloud/opcache.php just, if you did not apply the ht rewrite base in config.php or in case remove it and also comment out the related rewrite entries in .htaccess
