Sync speed limited to 30MB/s, WebDAV/php bottleneck?


Closed bugreport here:
Anyone here reached higher than 30MB/s with Nextcloud?
Nextcloud is awesome in everything but speed for copying large files, am looking for a way to improve it.
Have caching setup per documentation, tried fiddling with nginx/php settings without joy.

Edit: when monitoring a file transfer I see high CPU usage pegged at one core for processes of nginx and php-fpm.


Bumping the post.


I have a setup with similar computing power (running Apache without FPM) and tried to transfer a file with around 20GiB. Sometimes the upload would go up to more than 40Mbit but rarely stay that high. I also noticed that one Apache process constantly maxed out one CPU core.


another bump
