Description
I am trying to get my nextcloud setup tuned with nginx on debian.
I confirmed that my bandwidth is not a factor and you can see speedtest results at Speedtest by Ookla - The Global Broadband Speed Test.
I have it tuned so that no warnings appear in the administration page. When doing downloads, I have it working at a clean 100MB/s.
When doing uploads via browser, it is bottlenecked to 6-8MB/s.
When doing uploads via WebDAV, it performs around the same.
I do not believe this is a duplicate of other tickets because most others I read demonstrated little understanding of the web server configuration and didn’t provide complete config information.
I can’t figure out where the bottleneck is
Things I tried already
- Increasing php.ini memory_limit to 1G or 2G. This had no effect.
- Enabling/Disabling http/2 in Nginx Proxy Manager. I find enabling it improves webdav performance, but otherwise it has no impact on max upload speed.
- Testing Chunked vs Unchunked using a public upload link in incognito mode.
- Tuning linux kernel TCP settings in hypervisor. This did help to achieve the high download speeds.
