Recent increase in upstream response time on one of two Adguard DNS Servers #7399

Prerequisites

Platform (OS and CPU architecture)

Linux, ARM64

Installation

Custom package (OpenWrt, HomeAssistant, etc; please mention in the description)

Setup

On one machine

AdGuard Home version

Version: v0.107.53

Action

I have two adguard installations on my LAN. One is running standalone on a Raspberry PI4, the other is running as an addin in Home Assistant running on a Raspberry Pi400. Both have run quite well for a long time with fairly consistent upstream response times and processing times.

Expected result

Consistent upstream response time and similar performance from both adguard installations.

Actual result

Recently, the upstream response times reported on the Home Assistant instance have increased dramatically from an average between 10 and 70 ms, to as long as 2200 ms. Here is an example:

https://dns.nextdns.io:443 2241 ms https://freedns.controld.com:443/p1 1150 ms 172.30.32.3:53 846 ms https://dns.quad9.net:443/dns-query 413 ms https://doh.cleanbrowsing.org:443/doh/security-filter/ 43 ms

Upstream response times on the standalone Adguard instance remain below 30 ms for the same set up upstream servers. I've made no changes at all in any configuration on the HA Adguard settings.

I've also noticed increases in processing time, but much less dramatic. In the past processing time was usually 2m, now it's about 12 ms.
