I have now also adapted my www.conf + restarted apache2 and php  
but there was no improvement.

```
[www]
user = www-data
group = www-data
listen = /run/php/php7.3-fpm.sock
listen.owner = www-data
listen.group = www-data
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
pm.max_requests = 500
env[HOSTNAME] = $HOSTNAME
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp

```

According to the article

> [@High cpu load on apache V16.0.0.5](https://help.nextcloud.com/t/high-cpu-load-on-apache-v16-0-0-5/62180/9):
>
> Since I user the Beta 17 CPU Load is very moderate. As you can see in the graphics before I upgraded CPU load was 100% (6 Cores in a vm). some before it was 50% or e bit more. So it tooks CPU power more and more sincs the Upgrade end of september. After I upgrade to the beta 17 its very low, you can see it also in the graphics.

updating to NC17 could resolve the problem  
… ???

When downloading a file it’s over this link:  
[https://mydomain.de/remote.php/webdav/ubuntu-18.04.2-live-server-amd64.iso](https://mydomain.de/remote.php/webdav/ubuntu-18.04.2-live-server-amd64.iso)  
May be there is a problem in remote.php or Webdav?
