The nextcloud is installed on bare linux on the synology DS, no docker-installation.
I run a cron job every 5 minutes, Also no issues. In the admin-panel of nextcloud usually always “green” and nextcloud confirms, that the last cron-job run few minutes ago.
output of the occ:
admin@srvconzel1:~$ sudo -u root ./nc_tools/occ ‘config:list core’ | jq ‘.apps.core.backgroundjobs_mode’
“cron”
Thanks for refering to the document of slow performance loading pdfs:
I would exclude the browser. It’s same behavour on different systems no matter which browser (edge, firefox, safari).
But I’ll review the other topics from that document.
One additional information: I face this issue since I did a complete new installation of my synology for some reason 4 weeks ago. Before it was running perfectly with no performance issues. After the basis synology system was running again, I did a new installtion of NC, then restored my data from a backup.
