I've been trying out this new branch for a few days and I looks like the memory consumption climbs over time. I've seen as high as 80% of my Pi5's 8GB, not all from Pi-hole of course, but most of it.
When I run htop I see a whole bunch of Pi-hole processes and as time goes on more and more show up. The more appear, the more memory is consumed. These 'extra' processes don't appear to have used any CPU cycles either.
This doesn't appear to happen on the development branch and the memory usage is definitely lower there too.
Here is what I see in htop:
