Problem:
NextcloudPi (LXC, installed by script) downloading files (<500 MB) via public internet, connection speed is very poor (transfer rates ~100KBytes/sec, bitrates ~1Mbits/sec, should be around 15 MB/s)
though via LAN within the local network download speed is fine (via public IP/ domain.name and without VPN).
Question:
What am I missing to debug and eliminate the bottleneck of the network(settings)?
I’m grateful for any help and hint!
Setup:
Proxmox running NginxProxyManager, AdguardHome and NextcloudPi as LXC, no firewall running yet, PHP 8.1
- NginxProxyManager as reverse proxy and load balancer with LetsEncrypt, http/2, force ssl and advanced NextcloudPi settings for getting carddav and caldav syncronized
- AdguardHome with DNS-over-TLS, with or without forced https
- NextcloudPi with Redis Server, Apache2
- Mullvad VPN with DNS server set to AdguardHome localIP
- here is my config.php:

What I tried so far following several net founds:
- debugging with iperf3, speedtest-cli and attempts to download from public internet
- Proxmox-kernel upgrade, with and without kernel parameter: “intel_idle.max_cstate=1”
- increased PHP memory limit to 512 and 1025 MB
- maximum file size: 10 GB
- enabled and disabled systemd-resolved
- nginx reverse proxy: custom locations= /dns-query. Advanced settings: proxy_request_buffering off; client_max_body_size 0; proxy_buffering off;
- adjusting MTU: using 1492 in the guest instead of 1500 which is set on the host
