[X] I have set up AdGuard Home correctly and configured clients to use it. (Use the Discussions for help with installing and configuring clients.)
Platform (OS and CPU architecture)
Linux, AMD64 (aka x86_64)
Installation
Custom package (OpenWrt, HomeAssistant, etc; please mention in the description)
Setup
On a router, DHCP is handled by the router
AdGuard Home version
0.107.44
Action
Open a single large web page (ie reddit home page) or multiple sites in tabs on a cold cache.
Expected result
Web page(s) open in a timely fashion.
Actual result
DNS queries stall on some or all of the pages due to the rate limit.
Additional information and/or screenshots
After installing AdGuardHome on my router, I noticed a intermittent stall in loading some web pages. Notably, 'large' ones or when loading multiple at once. After some testing I believe it's due to the default rate limit settings on AdGuardHome.
For example, loading the reddit home page on a cold cache will make upwards of 38 dns queries.
It is a sane default for most installations, and those who need it can always increase it or add clients to the list of ratelimit exceptions.
