Web server very slow

General Beta 6.0
1

Hi folks,

Having an issue where my web server seems to be very slow. To the point where my
Custom DNS record (pointing to the pi) takes a long time to resolve.

When using the IP of the Pi to connect to the web server, all the charts take a long time to load.

Rebooted and nothing since to fix it?

A few questions:

  • On which kind device do you run your Pi-hole on?
  • Is the device doing anything else than Pi-hole?
  • What is the load average on your system (see uptime)?
  • Are you using the web interface over HTTP oder HTTPS?
3

Pi 4 B - 4GB
Running HomeBridge and UniFi.
Average 0.58, 0.55, 0.50

over HTTPS

This is unusual, it should be pretty responsive on a RPI 4B.

  • Do you see the same slowness over HTTP?
  • How many queries per 24 hours does your Pi-hole see?
5

Yes, same over HTTP. Around c100,000 queries.

I assume the c is a typo in the number above. Are all domains slowly resolving or is this specific to your custom DNS records? Could you maybe provide a screenshot from the Query Log page showing a few reply times for a few queries?

Morning,

Follow this thread since a few days, I‘ve the same issue. The web interface is loading slow, mostly into timeout. Behind the scenes, Pi-Hole is working well.

I am using a Proxmox LXC with Debian Bookworm, pi-hole installation is at the latest state.

Give me a sign how I can help.

Kind regards
Carsten

How does htop look like? Do you see any threads spinning at 100% CPU or something?

Just to make sure:
You are participating in the v6 beta test, or are you running the most recent regular Pi-hole 5?

10

Yep, Beta 6 in the latest version

No, CPU is at 2,6% at the moment.

I didn't saw the debug log (3 days ago), so maybe my questions are not relevant, but:

How many clients in the last 24h does your Pi-hole see?

Also, do you see the same slowness when you navigate to other Dashboard pages (like Settings or Query Log) or they are responsive?

At the moment it is not possible to come into the dashboard. Maybe every 10th try with long waiting times. I‘ve around 150 clients at my home (all around), 1,7Mio entry’s in my blocklist.

Try to install Proxmox (if you don’t have), take the Proxmox-Helper for pihole (it will install a LXC with pihole 5), disable the Webserver and install pihole 6 (you know better how to do). I had no problems around 2 weeks with this constellation, since last weekend the problems are there.

Kind regards
Carsten
