Whenever pihole is enabled, our internet is either extremely slow or unresponsive. Installed on pi4b
Expected Behaviour:
No effect on internet speed
Actual Behaviour:
Internet is extremely slow when pihole enabled
To clarify, is Pi-hole causing slow internet speeds, or is DNS resolution the slow process?
Your debug log doesn't show any abnormalities in DNS resolution.
Once the DNS resolution process is complete (the only part of an internet transaction involving Pi-hole), subsequent traffic between the client and the destination IP is completely independent of Pi-hole.
I will note that your DHCP server (your router) is distributing its own IP for DNS server, and not the IP of the Pi-hole on your network:

Your Pi-hole is at this IP:
192.168.1.228
Thanks for looking into this. Should my pihole distribute IP or should my router?
Either device can be the DHCP server. If you use the router, ensure that the Pi-hole IP is the only DNS server listed.
Addition discussion here:
From the client where you are seeing nothing blocked, from the command prompt or terminal on that client (and not via ssh or Putty to the Pi), what is the output of
nslookup pi.hole
nslookup flurry.com
nslookup flurry.com 192.168.1.228
