AdGuard Home setup guide

[emmitt]

Hej,
unfortunately, I only have an apu2 board in the OPNsense and I have the feeling that the OPNsense is somewhat overwhelmed with AdGuard and the following lists. The response time is getting worse and worse - especially at heise.de the page load feels slow.
I use: HaGeZi's Pro Blocklist, uBlock₀ filters – Badware risks and Perflyst and Dandelion Sprout's Smart TV Blocklist.

Would it make more sense to set up a Raspberry Pi with Adguard or could there be other reasons for the drop in performance?
