How to speed up webdav and gui on upload?

Hi,

I am running nextcloud on an odruid u3+ using an external usb3 stick to store my data.
Encryption is disabled in nextcloud.

I made serveral upload tests:

1 file (50 MB)

  • copy a scp (winscp client): 2900 KB/s.
  • copy a webdav(winscp client): 1900 KB/s

These values are not fast, but its ok for my usecase.

Copying pictures 35MB (66 jpeg files)

  • copy via scp (winscp client): takes 0 min, 18 sec. Winscp shows about 1900 KB/s
  • copy via webdav (winscp client) : takes 4 min, 10 sec. Winscp shows about 120 KB/s
  • copy via web frontent (vivaldi browser): takes about 2min, 30 sec.

I only measured each run once, but from my experience webdav is allways much slower than using scp.
What can I do to improve the webdav and GUI speed?

Same issue I have on downloading:

So how can I speed up the webdav / gui speed?
Thanks a lot,

This is i/o wait, this means you have to wait for operations in your file system.

You should use the available caching mechanisms:
https://docs.nextcloud.com/server/12/admin_manual/configuration_server/caching_configuration.html?highlight=caching

And of course have a look into the cache settings of your database as well. There are scripts that help you to find suitable settings (tuning-primer, mysqltuner), e.g.:
