Nextcloud version: 22.1.1
Operating system and version: Ubuntu 20.04
Apache or nginx version (eg, Apache 2.4.25): Apache2.4.41
PHP version (eg, 7.4): PHP 8.0.8
I have a LAMP-Stack running and i have the issue that while i upload big files to the cloud, the performance of the whole could goes down.
It is hosted on a vServer in a Datacenter vom IONOS with 400Mbit symettrical up and download.
Any idea what it could be and how to resolve that issue?
Is this the first time you’ve seen this error? (Y/N): N
You haven’t really provided any information for a starting point.
What do you mean by “performance”? Are you looking at CPU load? Network load? Is the memory swapping?
It gets slow when i am using the UI in the Browser and Cyberduck (WebDAV) as a client.
With the official Nextcloud-Client i don’t noticed any problems yet.
Ok, so resource utilization is looking pretty low. Suggests that you might be dealing either with a network limit or a queuing issue. A queuing issue might be caused by something like insufficient “max_children” in php.
However, I’m also now thinking about your “remote” network connection. So you have your nextcloud server running somewhere with symmetric 400 Mbps. But what about the where you are accessing it from while you are doing your upload test? Are you running a “big upload” from one client-side network and running your UI performance test from the same network? Or are you running from two separate client-side networks?
Here’s what I’m getting at; if you are doing both the upload and UI performance test from the same network, then the upload is probably saturating your upstream network, which is what is causing you poor performance. Not your server. A lot of cheap home routers do a terrible job of allocating bandwidth to short requests.
Thank your for the advice but i tried that.
I uploaded from one network and tried to use the UI from another Network… same problem.
What i am wondering is, that the problem only appears when i try to upload big and many files with Cyberduck or over the Gui. With the Nextcloud-Client i have no issues…
And when i am uploading the same amount of data directly to the server over SFTP i have also no problems.
