I've installed pihole on a Synology NAS (via a Docker container) and since switching over, the performance seems slower than my normal router setup. The setup I've used is to set pihole as the only DNS server in the UI of my router.
This morning, I noticed that all clients were not able to browse and after disabling and re-enabling the pihole, things started working again. When browsing to the admin dashboard, I'm getting the connection to the API lost message (something similar to that). Today, so far, DNS responses seem to be slow in that I am able to notice a clear distinction between what my older (router set to use 22.214.171.124 DNS) setup provided.
I've got a debug log at the time I last saw the API lost message and lost connectivity so hopefully that will help (available here: https://tricorder.pi-hole.net/8zzpgg8aw5) but so far, probably due to poor config, pihole is slower rather than quicker as I'd expect.
I've also had a look around at some posts on slow performance but as I've left my pihole setup at a fairly basic level, I'm hoping there's nothing that I have set that is causing the issue.
Any guidance would be appreciated as I'd like to get past this initial pain so that things work perfectly... so far, I'm loving the no ads internet experience... it's just the slow responses that needs addressing at this point.
Thanks in advance.
