Nextcloud cron is taking forever, and what I have noticed is that the SyncJob and PreviewEnhancementProcessingJob are the main issues.
When there are many users, these jobs take several hours to run. What is their actual purpose? Are they essential, or can they be removed from the cron script?
Steps to reproduce
/usr/bin/php -f cron.php
Expected behavior
Slow
Nextcloud Server version
30
Added a github issue for this as well : syncjob PreviewEnhancementProcessingJob taking forever · Issue #50811 · nextcloud/server · GitHub
