From https://www.nginx.com/blog/tuning-nginx/:
In most cases, running one worker process per CPU core works well,
and we recommend setting this directive to auto to achieve that.
There are times when you may want to increase this number,
such as when the worker processes have to do a lot of disk I/O.
Since some versions of Nextcloud, fonts are served as woff2, which is
not forwarded to index.php by the supplied nginx.conf. This leads to
nginx returning the dynamic index page instead of the static fonts.
