Very low performance - pages loading very slow with ~3+ users

malkiya · May 6, 2025, 10:40am

Hi!

I wanted to host Nextcloud Talk for my family, so I installed Nextcloud via NextcloudPi on my Proxmox cluster. However, pages are taking a very long time to load, typically around 10-30 seconds depending on the user. Messages are also taking approximately 5 seconds to send within Nextcloud Talk. I’ve tried reinstalling from scratch a couple of times, but the issue persists. I highly doubt this is a hardware issue, as my system is running on a Ryzen 7 7840HS with 16 GB of RAM allocated.

The performance seems acceptable when testing as a single user, but as soon as more users join, the situation deteriorates significantly, even with just 2-3 users online who are only chatting.

Here are the installation steps I followed:

Install NextcloudPi on Proxmox via tteck’s/community scripts
Edit config.php (most notably forcing ‘pl’ language globally and setting the domain)
Install Nextcloud Talk plugin
Configure Nginx Proxy Manager

Could anyone kindly offer some insights or suggestions on how to diagnose and resolve this? I would be really grateful for any leads as I am out of ideas and couldn’t find any relevant solution on the forum.

I have no clue, but without HPB, up, it is difficult, without a fast and perfect network it is even more difficult, and all running on proxmox is not as easy as one may think.
Good luck.

malkiya · May 7, 2025, 8:18am

Thanks for your answer! Doesn’t HPB improve calls performance only? I use it only for chatting as for now.

Network is fast and perfect (testing over local network, so 1Gbps symmetric)

not being a NextcloudPi user… only suggestion

don’t see settings for trusted proxies in your config though. that config is necessary for reverse proxy setup regardless which install method you’re using. see also Hosts & FQDN configuration

Thanks for your suggestion! Here’s the trusted proxies configuration:

  'trusted_proxies' =>
  array (
    11 => '127.0.0.1',
    12 => '::1',
    13 => '10.0.2.6',
  ),

10.0.2.6 is the address of my reverse proxy server.

I’ve also just set FQDN using the steps described in “FQDN for Nextcloud snap instance, vm or container behind reverse proxy with termination” but unfortunately, I can’t see any performance gain.

By the way, here’s the machine load graph from the last hour (basically none), while it still takes 20 seconds to load a chat via Nextcloud Talk

However, the server takes 25 seconds to respond and I can see some errors:

this doesn’t look right… that’s localhost and will reroute to DNS configured on localhost causing a loop. be sure that only your reverse proxy is listed as your single point of entry.

it could be an issue that you’re using IPv6 on that device… if IPv6 is active, then IPv6 is always preferred causing the mentioned delay until failing over to IPv4.

Alright, thank you for the tip! I’ve adjusted my config to:

  'trusted_proxies' =>
  array (
    0 => '10.0.2.6',
  ),

however, there’s no speed difference (image below), and sending messages via Nextcloud Talk app still takes ~10-18 seconds
