Updated Pi-Hole, now CPU Usage is Way over 100%

Please follow the below template, it will help us to help you!

Recently updated pi-hole and now see in the UI that my CPU is running at well over 100%, often around 175%, but spiking to 300-400% sometimes. I'm only using it for ad blocking - no DHCP or anything else. 27 device currently online, not all using pi-hole. Basic install - I barely know what I'm doing, so nothing fancy about this at all.

Expected Behaviour:

Less than 100% CPU usage.
Pi Zero W, hardwired to network, Raspbian 10, Pi-hole core 6.05, FTL 6.04, web interface 6.02.

Actual Behaviour:

Everything seems to be working fine, but my CPU is running way over 100%.

Update: cpu usage is below 50% today. I've done nothing. Thanks for all your help.

Investigation is going on.

awesome, thanks. i still see it spiking above 100%, but can't correlate it to any activity. i'll try to figure out how to recreate the ftl db when i get a minute.

You can try to go back to 6.04 as this release is still fine.
